Answer 2

Answer:

The correct answer is option (c)

Step-by-step explanation:

Given data,

5 values with each value equal to 5

Required to find,

the standard deviation of the data

Formula used,

Standard deviation is the most commonly used measure of dispersion.

It is defined as the positive square root of the arithmetic mean of the squares of all the deviations of the values from their arithmetic mean.

Here, all the values of the data are equal to 5, and hence the mean of the data is 5.

So, The deviations of the values from the mean are Zero and hence standard deviation is Zero

∴ The correct answer is option (c)
