Find this student's median quiz score

Answer 1

Median = 14

Explanation:

The question is asking us to find the student's median quiz score.

I will begin by arranging their scores from least to greatest:

11, 17, 20, 9, 16, 12

9, 11, 12, 16, 17, 20

Now we find the median.

The median is the number right in the middle, but for this problem, there are 2 numbers right in the middle: 12 and 16.

So I find their mean:

`\sf{(12+16)/(2)}`

`\sf{(28)/(2)}`

`\sf{14}`

Therefore, the student's median quiz score is 14.

Answer 2

Explanation:

To find the median quiz score, we need to arrange the scores in ascending order.

Given scores: 11, 17, 20, 9, 16, 12

Arranging them in ascending order: 9, 11, 12, 16, 17, 20

The median is the middle value of the data set when arranged in ascending order. Since we have six scores, the middle value is the average of the two middle numbers. In this case, the two middle numbers are 12 and 16.

Calculating the average of 12 and 16:

(12 + 16) / 2 = 28 / 2 = 14

Therefore, the median quiz score for this student is 14.
