h. Type in the scores shown in the table above.
i. Check the accuracy of your entries.
j. Save the data set by clicking the floppy disk image on the toolbar, top of the “Data
Editor”, giving it name Patients Measured Cholesterol.
Part B
You will be running descriptive and frequency statistics and report the outputs for the created
Patients Measured Cholesterol dataset in Part A.
Specifically, do the following for descriptive statistics:
a. Select “Variable View” and ensure that “Scale” appears in the “Measure” column
b. Click on “Data View” and “Analyze” near the top of the screen
c. Go to “Descriptive Statistics”, and click the “Descriptives” on popped up window

Specifically, do the following for frequency statistics:
a. Click on “Data View” and “Analyze” near the top of the screen
b. Go to “Descriptive Statistics”, and click the “frequencies” on popped up window
c. Get frequencies for Age and Cholesterol variables, but don’t forget to click the
“Statistics” button on frequencies window and select mean, median, mode, standard
deviation, and variance.
d. Click Ok.
e. Report the output.
Based on reported descriptive and frequency statistics outputs, answer the following questions.
1) What are mean, mode and median statistics for Age and Cholesterol?
2) According to mean, mode and median statistics, what kind of distributions we should
expect to have for Age and Cholesterol variables?
3) What are the standard deviations and variances for Age and Cholesterol?
4) Is there any relationship between standard deviation and variance statistics? Please
explain your answer.
Part C
You will be creating a histogram and boxplot graphs for the Cholesterol variable in the
created Patients Measured Cholesterol dataset in Part A.
Specifically, do the following for histogram
a. Click on “Data View” and “Graphs” near the top of the screen
b. Go to “Chart Builder” and select “Histogram” on the popped up window under “Gallery”
c. Drag the “Simple Histogram” to “Chart Preview” area and drop it

b. Go to “Chart Builder” and select “Boxplot” on the popped up window under “Gallery”
c. Drag the “Simple Boxplot” to “Chart Preview” area and drop it
d. Drag the Cholesterol variable from “Variable” section to “Y-axis of the graph.
e. Drag the Sex variable from “Variable” section to “X-axis of the graph.
f. Click Ok.
g. Report the graph
Based on reported graphs, answer the following questions.
1) Are there any outliers for Cholesterol variable? Please explain your answer.
2) According to the created histogram for Cholesterol variable, what can you say about the
distribution of the variable? Does it support your answer in Part B question 2?
3) According to the created boxplot, what can you say about female and male distributions?
