Answer 1

Answer:

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.
