Name_________________________________________________________ Date __________ 5.5 Median, Mode, and Range (continued) 2 ACTIVITY: When the Mean is Misleading Work with a partner. Read and re-read each statement. Think of a better way to represent the “average” so that the statement is not so misleading. a. Someone is trying to criticize a small high school by saying “Last year, the average age of the graduating class was 22 years old.” When you look into the facts, you find that the class had a senior citizen who went back to school to earn a diploma. Here are the ages for the class. 18, 18, 18, 18, 18, 17, 18, 19, 18 ,18, 18, 18, 18, 74 What percent of the ages are below the mean? b. There is a small town where most of the people are having a difficult time getting by because of low incomes. Someone is trying to ignore the problem and writes an article in the newspaper saying “It is not so bad in the town. The average income for a family is $52,000 a year.” Here are the incomes. $20,000, $20,000, $20,000, $20,000, $30,000, $30,000, $30,000, $30,000, $40,000, $40,000, $40,000, $50,000, $50,000, $50,000, $310,000 What percent of families have incomes below the mean? What Is Your Answer? 3. IN YOUR OWN WORDS Describe situations in real life where the mean is not a good representation of the average.
