If the variance of a variable is 100, the standard deviation will be 10.

WHAT IS STANDARD DEVIATION:

  • Standard deviation is a measure of dispersion used in statistics to show how far a variable is from the mean. The standard deviation is denoted by S

  • The standard deviation is the square root of the variance (S²). Hence, if given the variance of a variable, we can easily calculate the standard deviation.

  • Therefore, in this case, if the variance of a variable is 100. The standard deviation can be calculated as follows:

S = √100

S = 10.

Therefore, If the variance of a variable is 100, the standard deviation will be 10.
