Questions about Comparing More Than Two Groups in SAS (continued).
(written at Notre Dame to cover material in Chapter 8 of SAS System for Elementary Statistical Analysis)
Click on the answer you think is most nearly correct.
1. In SAS if you fail to use a VAR statement with PROC MEANS:
PROC MEANS will not run. PROC MEANS will run with all of the variables in the data set summarized. PROC MEANS will run with only the nonnumeric variables summarized. PROC MEANS will run with all numeric variables in the data set summarized. PROC MEANS will run with only the most recently used variables summarized.
2. The Kruskal-Wallis Test is performed using:
PROC GLM. PROC UNIVARIATE. PROC FREQ. PROC ANOVA. PROC NPAR1WAY.
3. Data for group analysis are considered balanced if:
All groups have the same number of variables. All groups have the same number of observations. The means of the groups are equal. The variances of the groups are equal. There are as many observations above the mean as there are below the mean.
4. The following is not an assumption of analysis of variance:
observations are independent. observations are sampled from normal distributions. groups have equal means. groups have equal variances. measurement for one item cannot affect the measurement for another item.
5. The Kruskal-Wallis Test is not used with:
ordinal data. nominal data. ratio data. interval data. discrete data.
