Independent variable

For your indneendent variable x
a. Calculate separately the Minimum Value, Maximum Value, Range, Ql, Median, Q3, Interquartile Range, Mode, Mean, and Standard Deviation. (total 10 marks). b. Construct a separate Grouped Frequency Distribution Table. Create 4.5 class intervals and calculate Frequency, Cumulative Frequency, Relative Frequency, Percentage Relative Frequency (total 10 marks) c Construct a Pie Chart and a Bar Graph, demonstrating the organization of values into class intervals (should include titles and numerical displays). (total 10 marks) d. Describe and comment on the Pie Chart and Bar Graph IS marks)
PART 2 (total 25 marks):
For dependent variably v
a Calculate the Minimum Value, Maximum Value, Range. Q1, Median, Q3, Interquande Range, Mode, Mean, and Standard Deviation (total 10 marks) b. Describe and comment on your findings (total IS marks)
DART 3 (40 marks):
For both your independent variable x and your dependent variable I, a. Calculate Pearson’s r to find if there is a correlation between the two variables. (5 marks) b. Conduct a Lineal Regression analysis to see of changes in the independent variable x can predict changes in the dependent variable y.
