Now we're going to look at whether memory for seeing broken glass (vs. not recalling broken glass) is dependent on whether the participants were asked about speed using the words "smashed" or "hit".

Category	Saw Broken Glass	Didn't See Broken Glass	Totals
"smashed"	16	34	50
"hit"	7	43	50
Totals:	23	77	100

1. How many variables are there in this example? How many levels of any variables are there?

1. What kind of chi-square test should you use (goodness of fit or test of independence)?

1. What are the null and research hypotheses?

1. Calculate the chi-square obtained statistic. Hint: use the formula below to find the expected frequencies per cell.

1. What is the degrees of freedom and the chi-square critical value if alpha = .05?

1. What is your conclusion: should you reject the null or fail to reject the null?What does this conclusion mean in plain English?
