Use the dataset College Students for this exercise.
Compute skewness for scale variables and for ordinal variables with more than five levels. (Look at the variable
view for the ordinal variables. Click on Values –the three dots at the right bottom of the space. If there are five
or more codes located there then that is an ordinal variable with five or more levels). Comment on the
importance of the skewness of the data. What does it mean and why is it important.
Which variables are nominal? Run Frequencies for nominal variables and ordinal variables with less than five
levels. Comment on the results (Hint: Percentages).
Do boxplots for student height and hours of study. Comment on outliers.
