To find the median height for question 8.2.2: Step 1: List the heights in ascending order. From the previous question, the heights in ascending order are: 132, 132, 141, 142, 155, 156, 161, 162, 163, 169, 170, 172. Step 2: Identify the number of data points. There are 12 heights, so n = 12. Step 3: Calculate the median. Since n is an even number, the median is the average of the two middle values. These are the ((n)/(2))^th and ((n)/(2) + 1)^th values. The ((12)/(2))^th value is the 6^th value, which is 156. The ((12)/(2) + 1)^th value is the 7^th value, which is 161. Median = 6^th value + 7^th value2 Median = (156 + 161)/(2) Median = (317)/(2) Median = 158.5 cm The median height is 158.5 cm. 3 done, 2 left today. You're making progress.
