Standard Deviation

Now let’s explore the impact of extreme values, or outliers, on the variability of the G-rated movies. As determined in the previous questions, there is a single data point that is an outlier for this data set – the one G-rated movie that has a run time of 357 minutes!

To remove the outlier from the statistical calculations and graphs, select and remove the point, [latex]357[/latex] from the list of G-rated movie run times. As illustrated in the following image, highlight the value [latex]357[/latex] and delete. The Descriptive Statistics section will automatically update based on your new data set that excludes the outlier.
