Exam 16: Non-Parametrics Revisited: the Ordinal Case

The ANOVA by ranks was created by

The Friedman ANOVA by ranks does for ordinal data what the U test does for interval data

When doing the ordinal T test, it is important to establish

Homogeneous variability within the various sample groups is required in order to calculate the

The T for correlated samples was created by

If a Spearman r were used on data requiring a Pearson r, then in order to obtain significance

The Type 2 error may only occur when the null hypothesis is accepted.

The more powerful a given statistical test is, the more likely it is to

The most appropriate measure of central tendency on ordinal data is the

In terms of the amount of information being contained in the measures, the following measurement scales rank

Ordinal tests of significance are all

Of the following, which may be used for the analysis of post-facto data?

When the conversion is appropriate, it is always possible to convert

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 .05.

Homoscedasticity is required in order to calculate the

For questions below, use the following: A researcher sets up a one-group, repeated-measures experimental design. Because the original, interval measures were badly skewed the data were converted into ordinal form. Subject \# Pre-Rank Post-Rank 1 1 1 2 3 2 3 2 7 4 5 3 5 7 4 6 6 8 7 8 9 8 10 5 9 9 6 10 4 10 -Indicate the critical, tabled value of T at .05

The Spearman r does for ordinal data what the Pearson r does for interval data.

The Friedman ANOVA by ranks is the ordinal equivalent of which interval test?

For questions below, use the following: A researcher sets up a one-group, repeated-measures experimental design. Because the original, interval measures were badly skewed the data were converted into ordinal form. Subject \# Pre-Rank Post-Rank 1 1 1 2 3 2 3 2 7 4 5 3 5 7 4 6 6 8 7 8 9 8 10 5 9 9 6 10 4 10 -Calculate the appropriate statistical value.
