Question
100%
Is gender independent of education level? A random sample of 395 people were surveyed and each person was asked to report the highest education level they obtained. The data that resulted from the survey is summarized in the following table:

High School​Bachelors​Masters​Ph.d.​Total

Female​      60​​     54​​   46​​41​201

Male​      40​​     44​​   53​​57​194

Total​    100​​     98​​   99​​98​395

Question: Are gender and education level dependent at 5% level of significance? In other words, given the data collected above, is there a relationship between the gender of an individual and the level of education that they have obtained?

A. Calculate the expected counts for each category and enter your results in the table below.

Table of expected counts:

 

High School

Bachelors

Masters

Ph.D.

Totals

B. Next, calculate the contribution to Chi-square for each category and enter in the table below.

Table of Chi-square contribution by category:

 

High School

Bachelors

Masters

Ph.D.

Totals

Female

 

 

 

 

 

Male

C. Finally, calculate the overall Chi-square and, after determining the degrees of freedom for the study, use the table of critical Chi-square cutoff values on the next page to determine if there is a relationship between gender and education level using the 5% (P=0.05) level of significance.  Now review your data and explain what the actual differences are between males and females with respect to education level achieved.
