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 .05 level.

All non-parametric tests are also distribution-free.

For the following distribution of interval scores, indicate, in order, the correct rankings. 799, 522, 515, 515, 515, 515, 515, 500.

Interval data may always be converted into ordinal data.

Conditions which tend to increase beta, also increase power.

Of the following correlation coefficients, which requires ordinal data?

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 -Calculate the appropriate statistical value.

The U test was created by

For the following distribution of interval scores, indicate, in order, the correct rankings. 110, 55, 55, 50, 42, 42, 42, 30, 27

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. -Calculate the appropriate statistical value.

Establishing whether the difference between two independently selected sample means is significant, requires the

The hypothesis of difference may be tested by using

Of the ordinal tests presented in the text, the only one which demands a reject of Ho when the obtained value is smaller than the critical, tabled value, is the

Whenever non-parametrics are used instead of parametrics, and the parametric assumptions are met, then

With the ordinal data, the important information being provided concerns

The U test makes no assumptions regarding the population parameters.

Ordinal tests may be used to test data from the

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 -Indicate the critical, tabled value at .01.

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 -Should Ho be rejected?.

The assumption of a normal distribution within the underlying population of scores, is required with the
