Answer:
Variance σ² having standard deviation 2.5 is 6.25.
Step-by-step explanation:
The standard deviation is basically the square root of the variance.
So, if want to find the variance of the data we simply take square of standard deviation to get the variance of data.
standard deviation = σ = 2.5
taking square on both sides
(σ)² = (2.5)²
σ² = 6.25
So, variance σ² having standard deviation 2.5 is 6.25.
