  1. Divide the sum by the number of terms. 502 + 477 + 593 + 481 + 735 + 614 6 3,402 6 = 567 Simplify. The mean is 567 COURSE 2 LESSON 1-10 Mean, Median, and Mode Find the average of 502, 477, 593, 481, 735, and 614. 1-10

  2. COURSE 2 LESSON 1-10 Mean, Median, and Mode Find the outlier of the data below. Describe how the outlier affects the mean. 40 37 53 42 45 12 39 48 The outlier is 12, which is much lower than the other data items. The outlier lowers the mean of the data. 1-10

  3. 18 Responses to “How many pizzas did you order?” 2 0 1 2 4 2 1 0 3 2 0 8 0 1 2 3 0 1 First write the data in order from least to greatest. 0 0 0 0 0 1 1 1 1 2 2 2 2 2 3 3 4 8 The two middle values are 1 and 2. = 1.5 Find the mean of the two middle values. 1 + 2 2 COURSE 2 LESSON 1-10 Mean, Median, and Mode Find the average of the data in the chart. The median is 1.5 pizzas. 1-10

  4. Favorite Pizza Topping of Twelve People Surveyed peppers onions mushrooms onions sausage peppers onions peppers mushrooms onions sausage onions Make a table to organize the data. Peppers Onions Mushrooms Sausage COURSE 2 LESSON 1-10 Mean, Median, and Mode Find the average of the data in the chart. The mode is onions. 1-10

  5. Multiply the weekday average by the number of weekdays. Multiply the weekend average by the number of weekend days. 2.5 • 5 + 4 • 2 = 20.5 COURSE 2 LESSON 1-10 Mean, Median, and Mode Suppose a teen jogs an average of 2.5 mi per day on weekdays and 4 mi per day on weekends. How many miles does this teen jog each week? The teen jogs a total of 20.5 mi each week. 1-10
