Exam 16: Non-Parametrics Revisited: the Ordinal Case

For the questions below, use the following: A researcher used a one-group, repeated-measure design, and established the following data: Scores Ranked by Rows Scores Ranked by Rows Subject \# Measure 1 Measure 2 Measure 3 1 1 2 3 2 1 2 3 3 2 1 3 4 2 1 3 5 3 2 1 6 1 2 3 7 1 2 3 8 3 1 2 9 1 2 3 10 2 3 1 -Indicate the tabled value at the .01 level.

Ordinal data may always be converted into interval data.

Of the following, which does not belong with the others?

If ordinal data were obtained from a three-group, matched-subjects design, then the appropriate test would be the

Since it has so few assumptions, chi square may always be used on ordinal data.

Regardless of the scale of measurement, the researcher analyzing data from a three-group, between-subjects design, must use the

For questions below, use the following: A researcher believes that athletic skill in basketball is a function of "handedness". A random sample of 24 professional basketball players was selected from the N.B.A., and divided into two groups according to preferred hand for shooting foul shots. The players were than ranked according to ability by a panel of sports writers. The data follow: Prefer Right Hand Prefer Left Hand 4 1 5 2 7 3 10 6 11 8 13 9 14 12 17 15 18 16 19 21 20 22 23 24 n1 =13 2=11 -Identify the type of research.

The ordinal test for assessing the difference between two correlated samples is the

The ordinal test for assessing the difference between two independent samples, is the

For questions below, use the following: A researcher sets up a three-group, repeated-measures design with random assignments of all subjects. All measures were originally taken in ordinal form. The data follow: Group 1 Group 2 Group 3 1 3 5 2 4 6 7 9 11 8 10 12 13 14 15 16 18 17 -Which statistical test should be used?

For questions below, use the following: A researcher wishes to find out if a speed-reading course increases reading speed. Sixteen subjects were randomly selected from the adult population and then randomly divided into two groups. Group A was given a speed-reading course, and then, because the interval scores were badly skewed, each subject was ranked according to reading speed. Their ranks were 1, 3, 4, 6, 8, 9, 10, 15. Group B received no training, and their ranks on the same test were 2, 5, 7, 11, 12, 13, 14, 16. -Which statistical test should be used?

In order to test experimental data via the U test, the design must be

When all the assumptions of the interval tests are not met, the researcher should use

For the ordinal T on small samples, with an obtained value of 17, and a critical, tabled value of 6.00, then

For questions below, use the following: A researcher believes that athletic skill in basketball is a function of "handedness". A random sample of 24 professional basketball players was selected from the N.B.A., and divided into two groups according to preferred hand for shooting foul shots. The players were than ranked according to ability by a panel of sports writers.

In order to test experimental data via the H test, the design must be

For a given sample size, the Spearman r is more powerful than the Pearson r

For questions below, use the following: A researcher sets up a two, matched-subjects experimental design, and collects ordinal measures on the subjects. The data follow: Group 1 Group 2 1 4 2 5 3 6 7 8 9 11 10 12 13 13 8 7 11 9 12 10 4 3 5 2 6 1 -Which statistical test should be used?

The ordinal test, cited in the text, for testing the hypothesis of association is the

For questions below, use the following: A researcher wishes to find out if a speed-reading course increases reading speed. Sixteen subjects were randomly selected from the adult population and then randomly divided into two groups. Group A was given a speed-reading course, and then, because the interval scores were badly skewed, each subject was ranked according to reading speed. Their ranks were 1, 3, 4, 6, 8, 9, 10, 15.
