Final answer:
The outlier can have a significant effect on the range of the data set and the standard deviation. Including an outlier in the data set can increase the range and the standard deviation.
Step-by-step explanation:
The effect of the outlier on the measures of variability is that it can greatly influence the range of the data set. When the outlier is included as the minimum value, the range will be larger than when the outlier is excluded. This is because the outlier is an extreme value that can pull the minimum value further away from the rest of the data points.
Additionally, the outlier can have a significant effect on the standard deviation, which is a measure of how spread out the data values are from the mean. Including an outlier can increase the standard deviation, as the presence of an extreme value can make the overall data set more spread out.
