Exam 14: Nonparametric Statistics

Which inferential procedure is appropriate when a study has one dependent variable measured on a nominal level and one independent variable measured on a nominal level?

What is the expected value for the upper left-hand cell of the following 2x2 table? 15 21 25 20

A basketball coach taught three groups of players to shoot free throws, using a different method for each group. After six weeks of practice, she ranked all of the players according to their ability to make free throws. Which test should she use to analyze these data?

What is the most important "conclusion-making" piece of information reported as the result of a chi-square, t-test, or ANOVA?

What is the nonparametric equivalent to a repeated-measures ANOVA?

What do we use to calculate the expected cell frequencies when applying chi-square to a data table to test independence?

Which nonparametric test would be the most powerful for testing for possible significant differences between two correlated samples?

When is a nonparametric test of significance most appropriate?

If the level of measurement for the dependent variable was ordinal and a nonparametric statistical test resulted in retaining the null hypothesis, which conclusion is LEAST defensible?

If N is 20 or greater, which table would you use to determine the significance of a Mann-Whitney U?

Which nonparametric statistical test is appropriate for a repeated-measure one-way ANOVA, if the dependent variable is measured at a dichotomous level?

A researcher had 25 subjects rank four types of workouts (running, swimming, biking, and aerobic dance) from hardest (1) to easiest (4). Which test should he use to determine if there is a significant difference among the ranking of the difficulty of the types of workouts?

Which of the following nonparametric tests is NOT used to assess association among variables?

What nonparametric statistical test is analogous to a one-way ANOVA with four levels of the independent variable?

A student answered 50 of 80 true/false questions correctly. Does this performance indicate that the student knew something, or was he just lucky? (Hint: Use chi-squared and α = .05.)

When would the use of a nonparametric statistical test be most appropriate?

Given that the number of winners from each starting position at the racetrack was as follows, what chi-square value is obtained? Does a relationship exist between winning and starting position? Position Winners 1 35 2 30 3 25 4 20 5 15 125 races

The Spearman rank order coefficient is MOST like which of the following?

Which of the following is LEAST like the others?

The percentages of scores falling below the following z-score values for a particular raw score distribution are: z -score of -2.04 5\% z -score of -1.04 20\% z-score of 0 55\% z-score of 1.04 90\% z-score of 2.04 100\% Does this distribution differ significantly from a normal distribution? (Use ? = .05.)
