A dot plot from repeated samples approximates the sampling distribution by showing the empirical frequencies of the statistic's values. It need not include every possible sample and can vary with the number of simulation repetitions.
Conditions: Repeated samples are drawn from the population.; A dot plot is constructed from the resulting statistics.

The video builds the histogram by repeatedly drawing samples of size 20 from a population, calculating the arithmetic mean of each sample, and recording that single mean as one entry in the histogram. As more means are added (up to 100), the histogram evolves from sparse bars into a smooth, bell-shaped curve.
Conditions: Sample size is fixed at 20.; Each repetition contributes exactly one mean to the histogram.; Up to 100 means are accumulated for visualization.
