Description: The mean of the waiting times in an emergency room is 80.2 minutes with a standard deviation of 10.5 minutes for people who are admitted for additional treatment. The mean waiting time for patients who are discharged after receiving treatment is 120.6 minutes with a standard deviation of 18.3 minutes. Which times are more variable?

Key Concepts

Mean

The mean is a measure of central tendency that represents the average value of a dataset. It is calculated by summing all the individual data points and then dividing by the number of points. The mean provides a central value around which the data is distributed and serves as a reference point for comparing other values in the dataset.

Standard Deviation

Standard deviation is a measure of dispersion that quantifies the amount of variation or spread in a set of data values. It indicates how much the values deviate on average from the mean. A higher standard deviation signifies that the data points are more spread out, while a lower standard deviation indicates that they are closer to the mean.

Variability

Variability refers to the degree of spread or dispersion in a dataset. It helps in understanding how consistent or inconsistent the data values are. By comparing measures such as the standard deviation, we can determine which group or dataset exhibits greater fluctuations or differences among the individual data points.
