1) Range = 41 years old. The ages of people in line for a roller coaster vary by NO MORE than 41 years.
2a) Interquartile range (IQR) = 38 pages. The middle half of the data varies by NO MORE than 38 pages.
2b) 468 pages is an outlier because when you check using the IQR, 468 is greater than 455. (398 + 1.5(38) = 455)
This video introduces measures of variation, including the range and interquartile range. We discuss how to calculate both of those measures and what they tell us about the variation of the data. The helps us understand if there are any outliers and also how spread out or close together our data is.
