Fictional data: In a sample of n=4,575 people, the mean number of hours spent on smartphones on a typical day was 4.72 hours. The standard deviation was 1.17 hours. Given this information, what are two 'numbers of hours' you would expect to see in the data, other than the mean itself? To answer this question, recall that standard deviation is the average amount that any single value deviates from the mean value. Have one of your 'expected hours' be below the mean, and one above the mean. ------------------------------- Extra credit: Is your own mean use of your phone above or below this (fictional) mean? By about how many standard deviations below or above the mean would your phone use be? (Round up to 1, 2, or 3 standard deviations above or below.) (Or more!)
