Question

standard deviation of a data 5 . if each value is multiplied by 2 then new variance ?

Answer 1

Answer:

10

Step-by-step explanation:

Answer 2

New Variance is 100.

• Standard deviation of data is 5.
• Variance of the data will be equal to 5² = 25.
• Formula to calculate variance is sum of squares of the data divided by the number of data sets.
• Now, when each data is multiplied by 2.
• The new variance will be equal to 2² × variance.
• New variance = 4 × 25 = 100.
