Step 1 of 9:

Calculate the Sum of Squared Error. Round your answer to two decimal places, if necessary.

Step 2 of 9:

Calculate the Degrees of Freedom among Regression.

Step 3 of 9:

Calculate the Degrees of Freedom among Error.

Step 4 of 9:

Calculate the Mean Squared Error. Round your answer to two decimal places, if necessary.

Step 5 of 9:

How much of the variation in the dependent variable is explained by the regression? Round your answer to two decimal places, if necessary.

Step 6 of 9:

What proportion of the variation is explained by the regression? Round your answer to two decimal places, if necessary.

Step 7 of 9:

What is the estimated variance of the error terms? Round your answer to two decimal places, if necessary.

Step 8 of 9:

What is the total variability of the dependent variable? Round your answer to two decimal places, if necessary.

Step 9 of 9:

What is the variance of the dependent variable? Round your answer to two decimal places, if necessary.

Answer 1

Source	SS	df	MS	F
regression	2268.900	2	1134.450	2.80
error	4056.600	10	405.660
total	6325.500	12

Step 1 of 9:

Sum of Squared Error =4056.6

Step 2 of 9:

Degrees of Freedom among Regression =2

Step 3 of 9:

Degrees of Freedom among Error =10

Step 4 of 9:

Mean Squared Error =405.66

Step 5 of 9:

How much of the variation in the dependent variable is explained by the regression =2268.90

Step 6 of 9:

proportion of the variation is explained by the regression =(2268.9/6325.5)=0.36

Step 7 of 9:

estimated variance of the error terms =405.66

Step 8 of 9:

total variability of the dependent variable =6325.50

Step 9 of 9: variance of the dependent variable =6325.5/12 =527.13
