How to find the number of standard deviations that it takes to represent all the data

The video tutorial explains how to determine the number of whole standard deviations needed to encompass all data values in a set. It begins with an introduction to standard deviation, followed by steps to reorder the data set. The tutorial then demonstrates calculating the first and second standard deviations from the mean. Finally, it concludes by determining the total number of standard deviations required to include all data values, emphasizing the importance of accuracy in calculations.

What is the significance of the second standard deviation in the context of the data set?

How many standard deviations are needed to encompass all of the data values?
