Answer 2

We need to recall the following formulas.

• $Mean=\frac{sum\space\ of\space\ numbers}{Total\space\ numbers}$
• $Standard\space\ deviation=\sqrt{\frac{\sum_{i=1}^n(x_i-\bar x)}{n} }$

Given:

The values are: $10,10,10,10,10,10,10,10,10,10$

The mean of the values is,

$Mean=\bar x=\frac{100}{10}=10$

Using the formula of standard deviation, we get

$sd=\sqrt{\frac{\sum_{i=1}^{10}(x_i-10)}{10} }$

Here, all values of $x=10$.

$sd=\sqrt{\frac{10(10-10)}{10} }$

$sd=\sqrt{\frac{0}{10} }$

$sd=0$

Hence, the standard deviation is $0$.
