Homework Answers
Solution:
12)
The______ measures the reliability of the estimation equation.
Answer :
c. Type 1 error
13. The________ is similar to the standard deviation in that both are measures of variability.
Answer : a. variance
To measure the variation in the data , we use variance or standard deviation.
standard deviation = positive square root of variance.
15.
The __________ is used to describe the correlation between two variables.
Answer: b. correlation coefficient.
correlation coefficient is a measure of linear correlation between two variables.
It lie in the range -1 to 1.
coefficient of determination = r2 It measures the explained variation in the response variable by the predictor variable.
