Question: Statistics Research Report:
This will consist of a statistical report on a business case study based on using various statistical techniques and SPSS.
HOW TO DO ASSIGNMENT
Because the data is already in a spreadsheet you can do Filea Open a select the spreadsheet in SPSS and will convert all data and variables into SPSS ready for them to use as a .sav file.
You will notice they need to do some tidying up such as remove text in some of the data, check variable view for correct use of data types.
All work is done through the Analysis menu:
Analyse a Descriptive a frequencies (choose statistics and charts to do the right stats and the histogram)
Analyse a Descriptive a Q-Q Plot
Analyse a Descriptive a Correlate a Bivariate
Analyse a Descriptive a Scale a Reliability Analysis (here they need to go into the options and choose "if item deleted" to get the results they need)
All output in the spv file can be converted to a Word document by doing File a Converta choose word document.
The data set you need to do the assignment can be found on Blackboard in the folder "Assignments and due dates" and in the spreadsheet "Data for Assignment 2".
This is a group assignment and you can submit the work in groups of up to 4 students.
You will need to complete the following tasks in SPSS and then submit the following files online under "Assignment 2 final submission". You will also need to print them out and submit them as well as a hard copy:
Activity 01:
Enter all data from the spreadsheet "Data for Assignment 2"into SPSS. You will need to set up the variable view with the following 11 variables and then enter the data in data view:
a) Student_ID,
b) Year_Enrolled,
c) HI001_Final_Exam,
d) HI001_Assignment_01,
e) HI001_Assignment_02,
f) HI002_Final_Exam,
g) HI002_Assignment_01,
h) HI002_Assignment_02,
i) HI003_Final_Exam,
j) HI003_Assignment_01,
k) HI003_Assignment_02.
Activity 02:
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.
Activity 03:
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?
Activity 04:
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?
Activity 05:
a) Copy -paste the data view and the variable view from your SPSS file to a Word document.
b) Copy-paste ALL the output from all the activities requested in Activity 01 to 04 in SPSS and put the answers in the same Word document.
c) Answer all discussion questions requested in Activity 01 to 04 and put the answers in the same Word document.
d) Submit a hard copy of Assignment 02 Word document to Holmes.
