Given this result from a chi-square goodness-of-fit test: 2(4) = 24.32, p <.01

a How many groups were compared?

b What was alpha?

c What was the critical value?

d Did the researcher conclude the difference was statistically significant?

Solution

(a) Number of comparisons = degrees of freedom = 4

(b) alpha = 0.01(Assuming that the p given is the required level of probability)

(c) Critical value = 13.277 (From the distribution table at k=4 and alpha=0.01)

(d) As the given value is greater than the critical value, the researcher did conclude that the difference was statistically significant.
