SAS Elementary Statistics Questions
(written at Notre Dame to cover material in Chapter 11 of SAS System for Elementary Statistical Analysis)
Click on the answer you think is most nearly correct.
1. Kendall's Tau-b statistic cannot be meaningfully used with:
Nominal data. Ordinal data. Interval data. Ratio data. Ordered data.
2. Expected cell values (EXPECTED) are calculated under the assumption that:
The variables are mutually exclusive. The variables are positively related. There are at least 20 observations. The variables are independent. The data are not ordinal.
3. Which of the following statement is not true:
When using Kendall's Tau-b statistic the order of the variables must be meaningful. A three-way table can be produced using only two variables. A 3 x 3 table can be produced using only two variables. A four-way table requires four separate variables. The chi-square test for independence makes use of the difference between the expected cell frequencies and the actual cell frequencies.
4. The following should not be used to analyze cross tablulations whenever some cells are empty or when some expected cell frequencies are less than five:
Fisher's Exact Test. The Chi-Square Test. Kendall's Tau-b. Sumers' D. Pearson Correlation.
5. Fisher's Exact Test is based on the following distribution:
Binomial. Hypergeometric. Chi-Square. Normal. Poisson.
