Answer:
mode is 47 because it appeared most in the frequency
median is 32
Explanation:
median =½ of the total of the frequency and the next position
½(40)th and the next position
½(20)th and 21th position
median= 32+32/2
= 64/2
= 32
The formula to find the mode of the grouped data is:
Mode = l + [(f1-f0)/(2f1-f0-f2)]×h.
Where, l = lower class limit of modal class, h = class size, f1 = frequency of modal class, f0 = frequency of class proceeding to modal class, f2 = frequency of class succeeding to modal class.
