Final Exam
Dr. Guy,

This test was extremely hard. Will you consider curving the grade?
Posted by      Ashley B. at 7:19 PM CST

  Dr. Rebecca Guy  says:
Yes. There will be a curve. I will work on it once the final exam has closed.

EXAM
PLEASE tell me there is going to be a curve on that final it dropped my grade over 11 points. That was so hard and I am freaking out.

Dr. Guy: Will you please consider curving the grades? The time allotted to take that exam (like the quizzes) does not allow for much time to go back and double check, which makes the anxiety increase and performance decrease, speaking on my behalf.
Posted on Fri, 8 Mar 2013 6:18 PM CST by Willie W.
  Dr. Rebecca Guy  says:
Yes. There will definitely be a curve.

Homework
I am just reading on the assignment where I actually misnumbered and missed a problem. Is it too late for me to go back and do it to get credit?

  Dr. Rebecca Guy  says:
At this point, it really is too late. I've graded over 200 assignments this week and if I were to accept resubmissions, I would probably have another 200 to grade.

Homework Assignment 2 Problem 7-2,3,4,5
I am going over my assignments now, can you help me on how to answer the following problems 2,3,4 & 5 questions, I missed them on my homework assignment.
Posted by      Melba M. at 12:02 PM CST

  Willie Williams  says:
For 7.2, you use the formula found on page 11 of Unit 5.
You're trying to find z.
Your X is your distance score, in this case, 128.
Your μ is 125
your α is 10.
Your formula will look like (128-125)/10=z.
Input your z score, which will equal .30 into the Standard Normal Curve calculator as one z score
Since we are trying to find the percentile below 128, we want to make sure all scores below (or to the left of) .3 are also accounted for, so we make the second z score -5 (any number greater than -4 will work)
You will get .61788 as your area, and you multiply by 100 to get the percent 61.788%

The same procedure for 7.3, except your first z score will come from plugging 99 into the formula, and the second z score will come from plugging in 107 into the formula.

7.4 and 7.5-- look on page 25 of Unit 5.

GHA5 #3
For 3-1 and 3-2 I am getting
-Positively
and
-Linear

are these two answers correct?
Posted by      James R. at 11:51 PM CST
Comments (1)
  Willie Williams  says:
Yes
Positively, because as X increases, Y is also increasing
Linear because you can easily draw a line through the plots

PSPP #8
It won't let me put numbers in past 25 in the columns. Has anyone figured out how to do so?
Posted by      Bilqis A. at 12:34 PM CST
Comments (2)
  Dr. Rebecca Guy  says:
I'm not sure why you are trying to enter 25 numbers. None of the SPSS/PSPP problems have data distributions that large.
Posted on Fri, 22 Feb 2013 1:21 PM CST by Rebecca G.
  Jherrel Jones  says:
Im confused on how we enter that one as well. Per the instructions we would have to enter 10 values within each group
1.0 9.8
1.0 9.9 etc... that's 40 how do we do this one???

Graded HW 4 problems 3,4,8,9
For the PSPP problems on the homework, are we doing the same for what we did on assignment 1 and 2? As in getting the PSPP image with the Mean, Standard Deviation, MIN, MAX, and Variance. Is there anything else we need to make sure is check marked before we press ok on the Descriptives?
Posted by      James R. at 7:03 PM CST
Comments (1)
  Dr. Rebecca Guy  says:
No. You are doing the procedure required for that particular problem (e.g. one sample t, t independent, analysis of variance, etc).

It is much more important to me that you do well than that you turn things in by a certain date.

Please do your best to meet the deadlines but if you miss them by a few days, there will NOT be any penalties.

For the PSPP problem do we just do the same steps for those numbers as we did on assignment number 1? I am slightly confused!!

Same Steps. But make certain you CHECKMARK both standard deviation and variance.

  Bilqis Abdul-Qaadir  says:
The lowest number is 2 and the highest number is 90....it says to start with 1 and have an interval width of 10. Your first interval should be 1-10, and so on until you get to 90. You find the interval width by: upper limit-lower limit + 1.. for this (1-10) interval you get 10-1 = 9... +1 = 10

Question
Does the computers on campus already have the program installed? Or, would it be better to install the program from my home computer, because I am having problems with both.
Posted by      John D. at 5:32 PM CST

  Dr. Rebecca Guy  says:
SPSS should be available from any Computer Lab on campus. You may need a thumb or flash drive for the data files.

Other than that, you should be able to run SPSS (PASW) without issue from any Campus Computer Lab.

Fill in the blank HW 1
Hey...can anyone help me out with #5? Not sure how to find the upper limit with just the interval width and midpoint.

Thanks,

Bilqis
Posted by      Bilqis A. at 9:32 PM CST
Comments (3)
  Dr. Rebecca Guy  says:
This is an interval with 11 unique values and 15 is the middle value. Hence, to create the interval, just place 5 values to the left of 15 (10, 11, 12, 13, 14) and 5 values to the right of 15 (16, 17, 18, 19, 20). The upper limit of the interval is the highest value or 20.

Technical Issues
Hello. I have attempted to download the PSPP and when I attempt to open it, Windows gives me an error message stating that it will not open it since it will be harmful to my computer.

This message is typical with Norton anti-virus. But the program is definitely VIRUS-FREE. Please continue with the install.

  Heather Gillespie  says:
Unfortunately, my computer will still not allow me to install the program. I have tried several times. I need to somehow override my computer to make in accept the install. Is there any way that I may be granted an extension on the assignment? I have all of it done except for number 9 and 10.

Saving the data image
I'm having trouble saving the image for problem 9 on assignment one. I have everything I need but I can't figure out how to save the data as an image. Help?
Posted by      Taylor M. at 8:44 PM CST
Comments (1)
  Dr. Rebecca Guy  says:
To save the output as an image file, you will need to use a SCREEN CAPTURE program. This is a program that will allow you to take a picture of your computer screen or some part of your computer screen.

Windows 7 & 8 come with a program called SNIPPET. Just open SNIPPET and capture the output window with the PSPP answer(s).

MACS (OS X) come with a program called GRAB. Just open GRAB and capture the output windows with the PSPP answer(s).

The data file is useless without software. PSPP is the software. Install PSPP first. Then double click on the PSPP icon to open the application (i.e. software). Now open the data file from within PSPP.

Posted by      Alexis B. at 5:18 PM CDT

  Dr. Rebecca Guy  says:
You solve number 8 exactly as you would solve number 9.

It is an Analysis of Variance problem -- not t.

Use the ANOVA - 4 Samples calculator.

Enter the values for WINTER in column 1.

Enter the values for SPRING in column 2.

Enter the values for SUMMER in column 3.

Enter the values for FALL in column 4.

Click the CALCULATE button to obtain the calculated value of F.

is this correct if not can you please tell me what is wrong?
h(0) μ =30
h(1) ≠ 30

assignment 4 question #4
does this question also require a t-obtained?

can you please explained it a little more im a bit confused on what to use as the test values since its saying a score between 0-25
Posted by      Alexis B. at 10:32 PM CDT

  Dr. Rebecca Guy  says:
Yes. You will need a calculated value of t (t obtained).

The statement that scores must be between 0 and 25 is just describing the lowest possible value for any score and the highest possible value for any score. The actual scores are listed for you and you should use the calculator labeled t IND - Raw Data.

H(0): μ(C) = μ(S)

H(1): μ(C) ≠ μ(S)

Hi, Dr. Guy I am still working on assignment for and almost done with the problem but having trouble figuring out which numbers go into the same t calculator

Hi, Dr. Guy I am not sure where to begin with this questions I have looked through sept 2010 blogs and Feb 2010 but still did not understand the full problem could you please explain so that I can answer these questions thanks.
Posted by      Alexis B. at 9:40 PM CDT

  Dr. Rebecca Guy  says:
For each of these problems:

State the Null Hypothesis
State the Research Hypothesis
Identify the Level of Significance
Look up the Critical Statistic
Compute the Test Statistic
State Decision (based upon a comparison of the critical and test statistics)

For Problem 3, you will need to first compute the mean for the sample of 9 values given in the problem. Then just use the One Sample t Calculator to find the test statistic.

For problem 4, use the calculator labeled t Test Ind. - Raw Data to compute the test statistic.

For problem 5, use the calculator labeled t Test Ind. - Sum. Statistics to compute the test statistic.

The level of significance is given to you in each of the problems.

Use the DISTRIBUTION OF t Table to find the critical statistic (based upon the level of significance and the appropriate number of degrees of freedom).

Practice Quiz Unit 8
Feeling a little frustrated. In the problem: An industrial designer wants to determine the average amount of time it takes an adult to assemble an easy to assemble toy. A sample of 16 times yielded an average time of 19.91 minutes, with a sample standard deviation of 5.73 minutes. Assuming normality of assembly times, provide a 95% confidence interval for the mean of the assembly time.
The formula I used was 19.92 = 1.96(5.73/square root 16)
My answer was 19.92 +- 2.81 but was incorrect

Im having trouble figuring out this problem. The way I thought I was suppose to work the problem is not giving me the correct answer. Please help. A random sample of 30 households was selected as part of a study on electricity usage and the number of kilowatt-hours was recorded for each household in the sample for the March quarter of 2006. The average usage was found to be 375kWh (s=81 kWh). Assuming the usage is normally distributed, provide an expression for computing a 99% confidence interval for the mean usage in the March quarter of 2006. I keep getting 375+- 38.16 and not is not an answer choice. I'm not sure what I am doing wrong.

Practice Quiz unit 7
Dr. Guy,
I'm having a hard time figuring out how to solve this problem on the practice quiz and where to start. The mean of a population of scores is 20 and the standard deviation is 6. What is the probability that the mean of a random sample of 4 cases drawn from the population will be greater than 23?
Posted by      Raven C. at 9:20 PM CDT
Comments (1)
  Dr. Rebecca Guy  says:
First, compute z:

z = (23 - 20)/(6/sqrt(4))

Once you have z, read the area to the RIGHT of z (since we are interested in greater than 23).

This area IS the probability.

assigment 3 questions 5
Ive checked the previous blog for this answer which was -3.43 do we plug the numbers into the one sample z calculator the same as we did in question 4. I am not coming out with this answer because I am not sure which numbers go into the calculators I know that the standard deviation is 3.5 we enter into the calculator and the sample mean is 9 what about the population mean and sample size. I am totally confused please help also is question 6 the same?
Posted by      Alexis B. at 7:20 PM CDT
Comments (1)
  Dr. Rebecca Guy  says:
For problem 5, the sample mean is NOT 9. The sample SIZE is 9.

To find the sample mean, you will need to compute the mean of the values 21, 15, 12, 24, 20, 21, 13, 16, and 11.

The population mean is 21.

The population standard deviation is 3.5

Once you compute the sample mean, you should be able to enter the values into the one sample z calculator and get the correct answer.

Yes. Enter as you have described.

If you check the standard normal distribution, you will discover that 2.5% of the area lies to the LEFT of -1.96 and 2.5% lies to the RIGHT of +1.96 or 5% of the area lies outside the boundardies of ±1.96.

Within the Negative Skewed Distribution the mode, median, and mean are pulled more towards the left and are also sometimes found to be clustered. The Mode is the highest point, the median is found in the middle and the mean is the lowest point.
Within the Positively Skewed Distribution the mode, median and mean are pulled more towards the right. The mode is the highest, median the middle and the mean being the lowest in the distribution.
Within the normal distribution, the mode, median, and mean all fall in the center. The mode is the point where the score that happens the most. The median is the middle of the score and the mean is the balance point. Thus making a perfectly, normal curve.

Comments (1)
  Dr. Rebecca Guy  says:
First read the area to the left of z = -2.00. You can do this using the STANDARD NORMAL CURVE calculator. Enter -2 for one of your two z scores. Technically, your second z score is infinity. However, you cannot enter infinity into the calculator. Since virtually 100% of area lies between z = -4 and z = 4, enter any z value smaller than -4 (e.g. -5, -10, -50 etc).

Since the curve is symmetrical, the area to the right of z = 2 is the same. You can confirm this by using the same calculator. Enter 2 as one of your two z scores and any number larger than 4 as the second z score (e.g. 5, 10, 50, etc).

Now add these two areas together.

Open the z/Percentile Rank Calculator.

1. Use the part of the calculator that uses Percentile to find z. Enter 25. Press Calculate.

2. Using the same calculator, enter 60 and press Calculate. Remember, Percentile Rank represents the PERCENT of scores BELOW z. The z score where 40% of scores fall above it is also the same z score where 60% fall below it. You can think of that z score as a dividing line with 40% above and 60% below. The 60% below would represent a percentile rank of 60. Hence enter 60 into the calculator.

  Dr. Rebecca Guy  says:
FALSE

They would all be identical if:

(1) all the terms were identical
(2) a distribution were perfectly symmetrical (with a mode)

I have never heard of that happening before. Can you try a different browser?

All of the calculators are written in JAVA and hence, should 'act' the same way on your computer screens.

journal
Professor Guy,
I read on the syllabus that your journal entry must be marked complete in order for it to be graded. How do you mark it complete and how do we submit it to you for it to be graded.

  Dr. Rebecca Guy  says:
MY JOURNAL works a lot like email.

Click on MY JOURNAL. Then click on POST TO JOURNAL,.

For the SUBJECT, enter the assignment number -- for example, Assignment 1.

Now beginning entering your answers:

1-1.
1-2.
1-3.
1-4.

etc.

You can stop at any time and click SAVE.

If you did not finish, you can come back to this journal entry at a later time and add to the assignment or edit your work.

When you OPEN the assignment the second time (after you have clicked SAVE at least once), you will see two buttons to the right of the journal title:

(1) mark completed
(2) edit

Continue editing the assignment until you have finished it.

Then once finished, click MARK COMPLETED.

At this point, you will no longer be able to edit the assignment and I will grade it.

agree with this. i'm really close to being done w/ everything, but there is no way i can have it turned in by tonight @ midnight. i totally understand that if everyone turned things in at the very last minute, then Dr. Guy would be swamped with grading. but hopefully sunday to monday will still be okay! *fingers crossed*

pSPP-Assignment #5
I am having a hard time with the PSPP. Once I input the data and try to analyze it Im not sure where to go from there. I was able to use the links in the syllabus at first (The ones that put the data into pspp for you then u just analyze from there but that isnt working anymore, for whatever reason). Can someone tell me what I am supposed to do after I input my data into PSPP for assignment 5#3?

Posted by      Tywona M. at 11:58 AM CDT
Comments (2)
  Dr. Rebecca Guy  says:
You are probably adding SPACES. Please re-read the instructions:

In assignments 2 and 3, you may need a few GREEK symbols.

Here's how to get them.

Type & s i g m a ; (I've included spaces here to show you the exact string of characters needed BUT NO SPACES when you type it) to get σ. PLEASE NOTE: You MUST include the & and the ;

Type & m u ; (I've included spaces here to show you the exact string of characters needed BUT NO SPACES when you type it) to get μ. PLEASE NOTE: You MUST include the & and the ;

Type & s u m ; (I've included spaces here to show you the exact string of characters needed BUT NO SPACES when you type it) to get ∑. PLEASE NOTE: You MUST include the & and the ;

In other words, the & and ; are part of the string you must type.

& s i g m a ; (no spaces please) = σ

& m u ; (no spaces please) = μ

& s u m ; (no spaces please) = ∑

& a l p h a ; (no spaces please) = α

& n e ; (no spaces please) = ≠

& p l u s m n ; (no spaces please) = ±

(Previous Blog Entry) Dr. Guy I just want to make sure I'm doing the problem correctly. Is this how it's supposed to be?

H(0): μ = 21
H(1): μ � 21

Dr. Rebecca Guy says:


Yes. They are correct.
Posted on Mon, 19 Sep 2011 3:08 PM CDT by Erica R.
  Dr. Rebecca Guy  says:
If you will notice in parentheses at the end of problem 3, you are told that this problem requires the ONE SAMPLE T CALCULATOR.

First, you will need to use the DESCRIPTIVE STATISTICS calculator to find the MEAN and STANDARD DEVIATION of the sample of 9 values given to you.

Once you have these values, open the ONE SAMPLE T CALCULATOR and enter 21 as the population mean. Then enter the sample mean and standard deviation that you calculated and 9 as the sample size. Click CALCULATE.

You should get an obtained t value of -2.59.

The previous BLOG entry refers to a t test for independent samples. The assignment HAS BEEN CHANGED since that blog entry.

Posted by      Erica R. at 5:06 AM CDT
Comments (1)
  Dr. Rebecca Guy  says:
The 'trouble' can stem from many factors including your browser settings, your virus software, etc. In other words, it is virtually impossible to troubleshoot like this.

If you want to run SPSS, you can complete the SPSS part of the assignment in any campus lab or you can go to the IT office and they will try to assist you.

You can also download PSPP (which is an SPSS lookalike program) free of charge. The download link can be found on page 3 of the syllabus.

I have provided SPSS and PSPP instructions under the menu option labeled SPSS/PSPP INSTRUCTIONS. If you compare these instructions, you will see that they are virtually identical.
