Question

find the mean,median, mode and range
40 45 46 40 57 23 65 40 43 45 45 23

Answer 1

Step-by-step explanation:

In the given data, Mean = Sum of observation ÷ No of observations

So, 40+45+46+40+57+23+65+40+43+45+45+23 ÷ 12

= 512÷ 12

= 42.667

Mode = Most times ocurring number in the data

So, 40 and 45 occur 3 times each

So, 40 and 45 is mode

Range = Highest number - lowest number

= 65-23

= 42
