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 for the population being studied. The range is a measure of variability or dispersion of data, which is represented by the variance in a normal distribution curve. The bell-shaped curve represents the distribution of data around the mean value, which is the highest point on the curve. Frequency distribution is a way of displaying data in a table or graph that shows how often each value or range of values occurs. Therefore, the best answer is C, variance.
