SAT Data Analysis Student-Produced Response

Correct Answer: 115

Solution:

Tip: If $n$ numbers are arranged in increasing order, the median is the middle value if $n$ is odd, and it is the average of the two middle values if $n$ is even.
Tip: In a set of numbers, the mode is the number that appears most frequently.
We arrange the temperatures in increasing order: 50, 50, 51, 54, 56, 56, 57, 59, 59, 59, 60. The median is 56 and the mode is 59. The sum of the median and the mode is 56+59=115.

Common Mistakes:

• Not arranging the data in increasing order before finding the median.
• Finding the median only, or the mode only, not their sum.

If you get this problem wrong, you should review SAT Mean, Median, and Mode .
