Sampling distributions are typically distributions of means of samples rather than of what?

• A. Means of samples
• B. Individual values
• C. Medians
• D. Variances

Answer: (A)

A sampling distribution shows how a statistic computed from samples would vary if you repeated the sampling many times. The most common statistic to look at is the sample mean, so when you take many samples and compute each mean, you get the sampling distribution of the mean. This focuses on the behavior of the statistic across samples, not on the raw data points themselves. The distribution of the individual values you observe in a single sample reflects the population (or the sample’s data) rather than a repeated-sampling behavior of a statistic. Medians or variances can have their own sampling distributions, but the classic idea emphasizes the mean because it summarizes central tendency and its variability across samples. So the idea described is that sampling distributions pertain to the means across samples rather than to the actual individual values.
