Question

The weights of 7 gentlemen are given below
75 kg, 70 kg, 68 kg, 64 kg, 77 kg, 65 kg, 74 kg.
Find the range, mean, median and mode of the
data.​

Answer 1

Answer:

Step-by-step explanation:

Range = (highest value - lowest value) = 77 - 64 = 13

Mean = (sum of terms)/(number of terms) = 493/7 = 70.42

Median = Exact middle number in a set of numbers in ascending order = 70

Mode =  Number repeated the maximum times in a set of numbers

          = 3 median - 2 mean

          = {3 × 70} - {2 × (70.42)} = 210 - 140.84 = 69.16

Hope it helps!!
