Your first statement is one of the two properties. The second is not.

Please see Unit 3 for these two properties.

Convert 99 to z form.

Convert 107 to z form.

Read the area between the two z scores.

Multiply by 100 to convert to a percent.

If you have time to meet with me in my office, I would be happy to assist.

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.

If the standard deviation is the SQUARE ROOT of the variance, then the variance is the SQUARE of the standard deviation.

Thank you...

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.

Perfect isn't necessary. :)

Ashley:

Please see the syllabus for information on SPSS/PSPP. Also, please see the link labeled SPSS/PSPP Instructions.

If more help is needed, please make an appointment to see me in my office.

Can I meet with you today, Dr. Guy?

Most of these answers can be found by reading older blog messages.

Snapshot is freeware. Please download from this page:

I'm using Firefox and it's saying that the free trial is no longer available and I have to purchase it.

You can if you like or you can use the calculators at the following link:

NVM, just read old blog post explaining it. (Jan 22, 2010)

Correct

Just type it into the journal. It is OK if the columns do not line up perfectly -- as long as I can discern what you have.

Please see blog entries from previous semester for very specific help on this answer.

You will need:

Class Intervals
Absolute Frequencies
Cumulative Absolute Frequencies
Relative Frequencies
Cumulative Relative Frequencies

I have completed all of these for problem 6 of homework assignment 1 but my rF and crF are not coming out to .100 and 1.00. My Class intervals start with 1-10. My caF is 45. I'm not sure what it is that I have done wrong?

FALSE

They would all be identical if:

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

Read the eText in numerical order (Chapter 1 first, etc.).

The videos are not really part of this class and there are some videos whose content is not covered in this class.

They are only there to help.

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.

I started out with Google, then internet explorer, and finally Firefox and it still didn't show.

You can just RETYPE it or you can capture that section of your screen (the same way you capture SPSS/PSPP output) and upload it.

Can you meet with me this week in my office?

I need a bit of assistance as well what day would be great to meet you in your office?

I am in my office on Wednesdays between 3:00pm and 5:00pm.

Please tell me the name of the file you are trying to download so I can provide you more detail.

I hqve attempted to download the PSPP file for Assignment 1 but it only shows like this

$FL2@(#) SPSS DATA FILE GNU pspp 0.6.2 - x86_64-pc-linux-gnu

I dont know what im suppose to do with this information..

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.

No. Once you mark the assignment complete, I will grade it. I will grade each assignment only once.

Assignment 1 - Problem 6



Fifty students completed a ten-item Likert scale that was used to create a scale score measuring attitudes towards interpersonal violence. Respondents who scored high believed that in many situations a person could legitimately use physical force against another person. Respondents who scored low believed that in no situation (or very few situations) could the use of violence be justified.

2 7 17 8 32 53 23 28 9 90 17 13 17 17 23 19 16 10 20 47 20 66 5 25 17 10 12 90 40 45 8 11 22 12 20 15 32 25 10 60 80 30 70 15 52 20 29 70 66 55

In this problem, you have 50 VALUES or NUMBERS. Enter each of these 50 values and the stem plot calculator will create the stem plot for you.

how do I copy the plot onto my journal?

Students are still creating CourseStreet Accounts and joining the course. Hence, I have not yet created any of the quizzes.

Quiz 1 will be ACTIVATED by Friday, January 20.

The remaining four quizzes will be ACTIVATED by Friday, January 27.

Thank you!

SnapShot is a zipped file. First, download and extract the contents to the desired location on your hard drive. Now BROWSE to the file, SnapShot, and DOUBLE CLICK on it to open the application. You should now see a a small square frame outlined with a dashed line sitting in the middle of your screen.

You can drag this frame to any area of your screen. You can expand the frame to the entire screen by click on the square to the left of the X in the top right hand corner. Once you have 'framed' the area you want to capture, click on the small DISK image (right side and near top of the frame).

Give the file a name and store it in a location you have chosen. When capturing SPSS or PSPP output, please save in .jpg format and UPLOAD to your DROPBOX.

Would it be possible for you to look at it to make sure I saved it right? I thinkI did but having never done this before I am just guessing.

I saw that too. I'm a little nervous about it as well since this is the first online course I've ever taken. We do have the advantage of having everything provided and we can do it on our own pace. It's the final exam I'm worried about. x_x;;
