Pat recorded the weights of the first ten fish she caught and released at Mirror Lake this season. The weights were 8 lb, 6 lb, 9 lb, 6 lb, 7 lb, 5 lb, 7 lb, 6 lb, 23 lb, and 6 lb. What is the median of the data set?
A. 6
B. 6.5
C. -7
D. -7.5
To find the median of a data set, we need to arrange the values in order from least to greatest.
5, 6, 6, 6, 7, 7, 8, 9, 23
There are 10 values in the data set, which is an even number. To find the median, we take the average of the two middle values.
The two middle values are 7 and 8, so the median is (7 + 8) / 2 = 7.5
Therefore, the answer is B. 6.5.
