Parameters for a Binomial Distribution Practice Test

The mean is the number of trials n, and the standard deviation measures how much the probability of success p can be expected to vary from trial to trial.

The mean is the most likely number of successes in one set of n trials, and the standard deviation is the maximum possible deviation from this value.

The mean is the probability of success on a single trial, and the standard deviation is the measure of variability of that probability over n trials.

The mean is the long-run average number of successes over many sets of n trials, and the standard deviation measures the typical variation of the number of successes around this average.
