Determine the percent of samples that are between 27.7 mpg and 38.5 mpg. Algebra 1B Lesson 42. Instructional material 2. Standard Deviation. Standard Deviation . is a number that tells us how a value in the data set differs from the mean. It also tells us how spread out the numbers are. The bigger the standard deviation, the more widespread the data is..
