Question 1
2.5 out of 2.5 points
A researcher used chi square to examine toy preferences of 5-year-old children. The researcher placed a tricycle, blocks, a train set, and puzzles in a room and observed how many of 20 children played with each type of toy.
What is the alternative hypothesis for this study:
Selected Answer: b. Children will not play with the four types of toys equally.
Correct Answer: b. Children will not play with the four types of toys equally.
Question 2
Chi square is used to analyze variables measure on what scale of measurement?
Selected Answer: a. Nominal
Correct Answer: a. Nominal
Question 3
The two-way Χ2 is a test of
2.5 out of 2.5 points
0 out of 2.5 points
Selected Answer: a. goodness of fit of observed frequencies to population frequencies.
Correct Answer: c. whether two variables are independent.
Question 4
2.5 out of 2.5 points
If you are conducting a one-way chi-square for a study with 200 participants and 4 categories, what would the expected frequency be for a given category?
Selected Answer: b. 50
Correct Answer: b. 50
Question 5
2.5 out of 2.5 points
Suppose you conduct an experiment with 44 participants who are asked to respond to one of three categories. Your obtained chi square is 5.22, which is statistically significant. What is the correct way to report this finding?
Selected Answer: Correct Answer:
Χ2(2, N = 44) = 5.22; p < 0.05
Χ2(2, N = 44) = 5.22; p < 0.05
