Question

The following data is given:

4, 6, 7, 5, 3, 5, 4, 5, 2, 6, 2, 5, 1, 9, 6, 5, 8, 4, 6, 7.

Find: i) Mean ii) Range iii) Median iv) Mode​

Answer 1

Answer:

Mean = sum of observation/ number of observation

Mean = 100/20 = 5

Range = Largest observation- Smallest observation

Range = 9 - 1 = 8

Mode = observation which repeat maximum times = 5

Median =

arrange the data in ascending order

1,2,2,3,4,4,4,5,5,5,5,5,6,6,6,6,7,7,8,9

Median = (5 + 5)/2 = 5

Answer 2

Answer:

mean:5

median:5

mode: 5

range :?

Step-by-step explanation:

mean:

sum of observations
