a) Do a frequency table, histogram, normal Q – Q and the de-trended normal Q–Q for each one of the 11 variables.
b) Do descriptive statistics (mean, standard deviation, minimum, maximum) for each one of the 11 variables.
a) Do at least 10 different correlations between the any pairs of variables: For example:
o HI001_Final_Exam and HI002_Final_Exam
o HI001_Assignment_01 and HI001_Assignment_02
b) For each correlation discuss the results:
o Are they are positive/negatively correlated?
o Are they weak or strong correlations?
o What is the significance value?
o What does the significance value reveal about the data we have used?
a) Do a Cronbach’s alpha reliability test on the following 9 variables: HI001_Final_Exam, HI001_Assignment_01, HI001_Assignment_02, HI002_Final_Exam, HI002_Assignment_01, HI002_Assignment_02, HI003_Final_Exam, HI003_Assignment_01, HI003_Assignment_02.
b) Discuss the results.
a. What item/s can be deleted to improve reliability?
b. What items should never be deleted to maintain reliability of data?
c. How many items need to be deleted to achieve maximum reliability?
