Find the median of grouped data
HELP

Answer:
6
Step-by-step explanation:
Median = (n+1) ÷ 2
Median = total frequency which is 55 + 1 = 56 ÷ 2 = 28th term.
So to find this term you add the frequencies until you get 28 or a number higher than 28.
3+1+10+15 = 29.
We got 29 when we got to the column of shoe size 6. So the Median is in shoe size 6.
