Mode of coding for responses
Strongly agree,5; Agree , 4; neutral, 3; disagree, 2 and strongly disagree, 2
1) Run the chi-squared test to determine if responses between agree categories and disagree categories(2 categories), for each Likert item, occurred by chance. Show and interpret results of the chi-squared test.
Coded responses for 'agree' and 'strongly agree' were combined as one category. 'Strongly disagree and disagree' responses were also combined to form one category. These 2 categories are of interest. There are 12 Likert items.
2. Would Fisher's Exact test be more appropriate, and would it have produced a different outcome ? Please show.
