a coach had her players take an agility test. here are their scores: find the median score. points

Explanation:

Step1: Count the number of data points

Count the number of blue dots. There are (1 + 1+1 + 2+3 + 4=12) data points.

Step2: Find the position of the median

For (n = 12) (even number of data points), the median is the average of the (\frac{n}{2})th and ((\frac{n}{2}+ 1))th ordered - data points. (\frac{n}{2}=\frac{12}{2}=6) and (\frac{n}{2}+1 = 6 + 1=7)

Step3: List the data in order

The ordered data set (based on the number of dots per score): (1,5,7,8,8,9,9,9,10,10,10,10)

Step4: Identify the 6th and 7th data points

The 6th data point is (9) and the 7th data point is (9)

Step5: Calculate the median

Median(=\frac{9 + 9}{2}=9)

Answer:

(9)
