What sort of data is appropriate for chi square tests?
2.
Using a goodness of fit we can test whether a set of obtained frequencies differ from a set of ______ frequencies?
3.
Which of the following hypotheses would be suited for testing by a one variable chi square test?
4.
How do we calculate the degrees of freedom for a goodness of fit test?
5.
You are conducting a one variable chi square test to test the hypothesis that there are equal numbers of vegetarians, meat eaters, and vegans eating at the student union. The categories are vegetarian, meat eaters, and vegans. Having conducted a survey, you found 85 individuals were vegetarian, 122 ate meat, and 32 followed a vegan diet. What would the expected frequencies be in each cell?
6.
Examine the output on p. 268. How would these results be reported?
7.

14.
What does the Fishers Exact Probability test show?
15.
For a 2x2 chi square test, which of the following equations would be used to calculate the degrees of freedom?

Refer back to the example in question 14 which look at submission of essays and time planning. In terms of essay submission, number of early, late and on time students are counted. The number of students who planned their time was also counted, leading to two levels of time planning or not. How would this analysis be described?

One serious complication associated with the analysis of more than three levels (4 x 5) is?
