The variance of a sample is calculated as 25. What is the standard deviation?

Step 1: Understand that variance is a measure of how much the values in a sample differ from the average.
Step 2: Know that the standard deviation is a measure that tells us how spread out the values are in relation to the average.
Step 3: Remember the formula to find the standard deviation: Standard Deviation = √Variance.
Step 4: Since the variance given is 25, substitute 25 into the formula: Standard Deviation = √25.
Step 5: Calculate the square root of 25, which is 5.
Step 6: Conclude that the standard deviation is 5.
