Question

The numerical value of standard deviation can never be positive . True or False ​

Answer 1

Answer:

The numerical value of the standard deviation can never be Negative

Answer 2

"The numerical value of standard deviation can never be positive", this statement is completely false.

• The standard deviation lies in the range of 0 to 1.
• When we compare 2 unequal observations, the result is always greater than zero ie always positive.
• Standard deviation is the square root of the variance of the observations and the root always gives values either positive or zero.
• Therefore, the numerical value of the standard deviation can be positive. The value of standard deviation is always greater or equal to zero.
