My name is Newbie Nevertookstats, and I just started a job as a reporter at USA Today. I was just been handed a data set containing SAT and GPA info for 200 juniors at a certain university and my boss wants me to write an article on this for the next issue. Unfortunately, I've never taken a stats course, so I need your help! My report is due in 1 week, so please help me by then!

**From Dr. Sarah-
Each group should include the following in one report aimed at
the reporter. Be sure to use the checklist
as a guideline.**

Under File, release Open Worksheet. If necessary, use the double arrow to go to Places and then to Applications HD /Applications/Minitab 105/Data and scroll down and open grades.mtw.

**Three Histograms** Under Graph, release Histogram....
The X value under Graph 1 should be highlighted.

Double click on VERBAL. Create a VERBAL histogram by using OK.

Make the histogram smaller by clicking on the bottom right corner, and draging this up and to the left.

Copy the VERBAL histogram by using Copy Graph under Edit.

Paste the VERBAL histogram into Word by using Paste under Edit in Word

Explain to Newbie that this is a histogram of Verbal SAT scores, and explain in depth what kind of info he can read off - give some specific examples.

**Two Boxplots** Under Window, Close All Graphs.
Under Graph, release Boxplot....
The Y value under Graph 1 should be highlighted.

Double click on GPA. Create a GPA boxplot by using OK.

Make the boxplot smaller by clicking on the bottom right corner, and draging this up and to the left.

Copy the GPA boxplot by using Copy Graph under Edit.

Paste the GPA boxplot into Word by using Paste under Edit in Word

Explain to Newbie that this is a boxplot of GPA grades, and explain in depth what kind of info he can read off - give some specific examples. Some answers to include:

the highest 25%?

the middle 50%? (ie those students not in the highest or lowest 25%)

the lowest 25%?

Move to the Y value for Graph 2 and double click on MATH.

Under Frame, release Multiple Graphs... Choose Overlay graphs on the same page and then OK

In addition, answer the same questions that you answered for GPA (For the last question, notice that for MATH the median looks to be just about in the middle.)

**Three Linear Regression Plots** Under Window, Close All Graphs...

You can create a linear regression by going to
Regression under the Stat menu, then releasing on Fitted Line Plot. The Y
variable is the Quality and the X variable is the best predictor; then
