The variance of a dataset is 4. what is the standard deviation?
The standard deviation is the square root of the variance.
Given that the variance is 4, the standard deviation is √4 = 2.
To find the standard deviation, you need to take the square root of the variance.
1. Start with the variance: 4.
2. Take the square root of the variance: √4 = 2.
So, the standard deviation of the dataset is 2.
To find the standard deviation, you need to take the square root of the variance. In this case, the variance is given as 4.
So, the formula for standard deviation is:
Standard Deviation = √Variance
Plugging in the value of variance (4) into the formula:
Standard Deviation = √4
Taking the square root of 4:
Standard Deviation = 2
Therefore, the standard deviation of the dataset is 2.
