D) frequency distribution

Question

Quizplus · Accepted Answer

The difference between the lowest and highest values on the x-axis of a normal distribution curve represents the range of values in the population being studied. This range is a measure of the variability of the data and is captured by the variance, which is the average of the squared deviations from the mean. Therefore, choice C, variance, is the best answer. The other options (A, B, and D) do not directly relate to the range of values in the population.
