Question
Which of the following is NOT an example of an inferential statistical technique?*1 pointa. T-testb. Chi-square testc. Frequency distributiond. Regression analysis
Solution
The answer is c. Frequency distribution. This is a descriptive statistical technique, not an inferential one. Inferential statistics are used to make predictions or inferences about a larger population based on a sample of data. Techniques like the T-test, Chi-square test, and Regression analysis are all examples of inferential statistics. On the other hand, a frequency distribution is a summary of how often different scores or ranges of scores occurred within a sample, which is a form of descriptive statistics.
