Inferential statistical tests are used for all of the following except: a. describing a sample with means and standard deviations b. determining if results occurred by chance c. testing hypotheses by asking if there are differences between groups d. making assumptions about a population

a. Describing a sample with mean and standard deviation.

Step-by-step explanation:

Statistics can be categorized into descriptive and inferential statistics.

descriptive statistics uses data for descriptions through numerical analysis. It can be further divided in four parts.

Measures of Central Tendency (Mean, Median, and Mode) Measures of Frequency (Count, Percent, Frequency) Measures of Position (Percentile Ranks, Quartile Ranks.) Measures of Dispersion (Range, Standard Deviation)

Inferential statistics however is based on assumptions and conclusions and generalizations drawn from samples or checks.

options b to d are all examples of inferential statistics while option a is an example of descriptive statistics.
