Question

mean of n observation is 30 and median is 35 find mode of observation

Answer 1

using empirical formula
3 median = mode + 2 mean
thus mode = 3 median - 2 mean
= 3(35) - 2(30)
=105 - 60
= 45

Answer 2

Answer:

35

Step-by-step explanation:

We know that mode = 3×mediun -2×mean = 3×35-2×30 = 105-70 = 35

So, mode of observation is 35
