Class 130-140 140-150 150-160 160-170 170-180 180-190 190-200

Freq. 5 9 17 28 24 10 7​

Answer 1

Answer:

160 - 170

Step-by-step explanation:

Add all the frequencies first:

5 + 9 + 17 + 28 + 24 + 10 + 7 = 100

Divide the frequency total by 2 to find median:

100 ÷ 2 = 50th data

Calculate where the 50th number stands

5 + 9 + 17 + 28 = 59

So, this means the 50th person is in the geoup where frequency is 28

So, median = 160-170
