Question

The electricity bills (in rupees) of 12 houses of a certain locality for a month are given below:
324, 700, 617, 400, 356, 570, 312, 630, 584, 674, 754,700
Calculate the mean, median and mode of the data.​

Answer 1

Answer:

add each no. for mean and divide by 2

for median write all no.s in sequence and then use formula of n+1÷2 or n÷2

for mode take the largest no.

Answer 2

Answer: 551.75, 600.5, 700

Step-by-step explanation: First we need to set the data in ascending order as follows - 312,324,356,400,570,584,617,630,674,700,700,754

Mean = 312+324+356+400+570+584+617+630+674+700+700+754/12

         = 551.75

Median = 6th + 7th observation/2

            = 584+617/2

            = 1201/2 = 600.5

Mode = 700 (it counts 2 times)
