Question

what is the coefficient of variation of the following numbers?53,52,61,60,64​

Answer 1

The coefficient of variation of the following numbers  53,52,61,60,64​ are,

Step 1:

To find the mean of the above numbers,

x = 53+52+61+60+64 / 5 = 290/5 = 58

Step 2:

To find Standard deviation.,

S = √53² +52²+61²+60²+64² / 5  - (58²)

   =√16390/5 -3364   = √3386-3364

   =√22  = 4.69

Step 3 :

To find Coefficient of variation,

Coefficient of variation ( C. V) = ( S / X ) * 100

                        = ( 4.69 /58 ) * 100  = 0.0809 * 100

                        ⇒8.09

Answer 2

Answer:

CV = 8.09
