Question

1-35. read the math notes box for this lesson and review the information about how to find the median of a data set. then find the median for andy’s test scores: 76, 84, 93, 67, 82, 87, and 76.

Explanation:

Step1: Order the data set

First, we need to order the test scores from least to greatest. The scores are 76, 84, 93, 67, 82, 87, and 76. When we order them, we get: 67, 76, 76, 82, 84, 87, 93.

Step2: Find the middle value

Since there are 7 data points (an odd number), the median is the middle value. The middle position is calculated as $\frac{n + 1}{2}$ where $n = 7$. So $\frac{7+ 1}{2}=4$. The 4th value in the ordered list is 82.

Answer:

82
