55. The Sum of Squared Errors for a data set of 18 numbers is 49.What is the standard deviation?

Short Answer

Expert verified

The standard deviation of the Sum of Squared Errors for a data set of 18numbers is 1.65.

Step by step solution

01

Given information

Given in the question that the Sum of Squared Errors for a data set of 18numbers is 49with the standard deviation.

02

Explanation

The standard deviation of the residuals is,
s=SEEz-2
Where, SSE=49is sum of squared errors and n=18is sample size.

Substitute the values and the standard deviation is,
s=SEE4鈭�2

=4918

=1.65
