Variance of a constant number is _____?

2
1
0
None of these

Explanation

Variance measures the spread of values around the mean.

For a constant number, all values are the same, so there is no spread.

Formula: $Variance = \sum ( x _{i} - x ˉ )^ ^{2/n}$

Here, $x_{i} = x ˉ$ for all i → $(x_i - bar{x})^2 = 0$

Therefore, variance = 0.
