A local ice cream store kept track of how many cones it sold during a five day period last week and the data is
shown in the chart above. This is the median number of ice cream cones
sold.
What is 41 ice cream cones?
Explanation: Median is the number found in the middle of a set of data after the numbers have been put in order.
The data in order is 33, 39, 41, 43 and 49.
The mode of five different test scores is 89. Four of the scores are 89, 93, 78, and 85. This is
the fifth score.
What is 89?Explanation: Mode means the number found most
often in a set of data. In order for the mode to be 89, there has to be another score of 89 in the list.
Bill’s median of 7 different scores is 87.
Six of the scores are 99, 81,

What is 87?Explanation: Median means the number found in the middle of a set of data after the numbers have been arranged in order. The 6 given numbers in order are 78, 81, 82, 90, 93, and 99. Since the median of
all seven scores is 87, 87 must be the missing score.
Sally’s mean of 5 different scores is 4.
Four of the scores are 3, 8, 2, and 1.

What is 6?Explanation: The mean is the average of the set of
numbers. If the mean of the 5 test scores is 4, that must mean the test scores added together must be 20. (20 ÷ 5 = 4). The first four test scores add up to 14, so the fifth test score
must be 6.
