Question

The accompanying stem-and-leaf plot represents Ben’s test scores this year.

What was the median score for this set of data?

1) 73 2) 79 3) 80 4) 81

Answer 1

Answer is 80.

The Key shows you how to read the plot.

Cross out the smallest number (65), then the largest number (99). Then cross out the next smallest number (68) and then next largest number (99). Continue crossing out numbers like this until you are either left with 1 number which is the answer OR two numbers, there you will have to get the average of the two numbers and that is the answer.

In this case you are left with 79 and 81, the average is 80 which is your answer.

Answer 2

Median = middle number.

Step 1: List the numbers in order (65, 68, 72, 73, 73, 73, 73, 79, 81, 83, 83, 86, 87, 96, 99, 99)

Step 2: Find the middle number (if even, two numbers) (16 numbers / 2 = 8th number) 79 and 81

Step 3: Average of middle two numbers (79+81)/2 = 80

Answer = 80
