Question

A data set is displayed in the stem-and-leaf plot. What is the median of the data set?

A.21

B.22

C.23

D.24

Answer 1

So the middle leads to two numbers 22 and 24. Now just do\[\frac{ 22+24 }{ 2 }=23\]

Answer 2

here is what you need to know for the median

there are 10 pieces of data

so to find the position of the median

add 1 to the number of scores and then divide by 2

(10 + 1)/2 = 5.5

so the median is between the 5th and 6th scores...

since the stem and leaf plot has the data is in order...

count down 5 scores from the top...

so the median is the average of the 5th and 6th scores...

5th score = 22 6th secore = 24

median = (22 + 24)/2

median = 23

hope it helps
