Question

1 1) Ms Dunne is a campus dean and she believes that morning classes are often a great idea in theory, but that many people do not actually attend those classes. Lisa also believes that participation in other social activities, particularly Greek life (fraternities and sororities) may contribute to these student absences in morning classes, as many of their social activities take place on weeknights and may influence whether a student can get up on time. Lisa polls a sample of 200 students, 100 in a fraternity and 100 who are not, asking whether they almost always attend their 8 am classes, or whether they are often late/absent. Attend Classes Fraternity 27 Non-Fraternity 84 a. What is the independent variable? Late/Absent 73 16 b. What is the dependent variable? c. What test did you use to analyze the data? d. Is the test significant? How do you know? e. Write the statistical notation in APA style f. Report the findings in 1-3 sentences. Make sure to include the independent variable, the dependent variable, all relevant statistics and a summary,

Answer 1

Answers:

a) The independent variable is social activities that is Fraternity and Non-Fraternity.

b) The dependent variable is Attending a class that is Attend class and Late/Absent.

c) The Chi Square Independence Test.

d) From the Output P value= 0.0000

Since P value<alpha. The results are significant.

e)

H_o: Social Activities and Attending a Class are independent.

H_a: Social Activities and Attending a Class are not independent.

f)

Chi Square= 65.78

Degree of freedom=1

P value=0.0000

Small Probability of occurring by chance alone. Conclude that the association exists between social activities and Attending a class. (Null Hypothesis is rejected)
