Question

Match the following definitions. You have 2 attempts for each question, and can submit your work as you go to check.

slope, R squared, b0, residual, β0, y, x.

The predictor variable.

The response variable.

The proportion of variation in the response variable that is
explained by the model.

The predicted change in the response variable for a 1 unit change
in that predictor variable, holding all other variables
constant.

The population value of the response variable when all predictor
variables are zero.

-The distance between an observed value and it's predicted value on
the line of best fit.

Answer #1

x - The predictor variable.

y - The response variable.

R squared - The proportion of variation in the response variable that is explained by the model.

slope - The predicted change in the response variable for a 1 unit change in that predictor variable, holding all other variables constant.

residual -The distance between an observed value and it's predicted value on the line of best fit.

b0 , β0 - The population value of the response variable when all predictor variables are zero.

Match the statistics term with its BEST
definition.
Question 2 options:
A key requirement for using correlation and regression models is
to collect this type of data.
With bivariate data, the result of MINIMIZING the sum of squared
distances between the observed and predicted values (residuals) for
a linear model.
This quantity is computed by subtracting the observed response
variable from the predicted response variable.
With bivariate data, when one variable increases a second
variable decrease implies this relationship.

A.
When the distribution of residuals does not change as the
independent variable changes.
B.
Used to determine how much dependent variables changes if
independent variable changed.
C.
Difference between the predicted and observed values.
D.
Lower value means statistical significance at a higher
confidence level.
E.

outlier b) The explanatory variable c) A residual d) The response
variable
2. Which of the following statements is false:
a) The correlation coefficient is unitless. b) A correlation
coefficient of 0.62 suggests a stronger correlation than a
