The appropriate hypothesis test for an ANOVA test is: - THE
CORRECT ANSWER-Ho: all B = 0, Ha: at least one B=/ 0
In regression analysis, extrapolation is performed when you: -
THE CORRECT ANSWER-Attempt to predict beyond the limits of the
sample.
Data collected from approximately the same period of time
from cross-section of a population are called: - THE CORRECT
ANSWER-Cross-sectional data.
In regression analysis, the variables used to help explain or
predict the response variable are called the - THE CORRECT ANSWER-
Independent Variables
In regression analysis, if there are several explanatory variables,
it is called: - THE CORRECT ANSWER-Multiple regression.
, In regression analysis, the variable we are trying to explain or
predict is called the - THE CORRECT ANSWER-Dependent Variable
Which of these is/are especially helpful in identifying outliers. -
THE CORRECT ANSWER-Scatterplots
Outliers are observations that - THE CORRECT ANSWER-Lie outside
the typical pattern of points on a scatterplot.
A "fan" shape in scatterplots indicates: - THE CORRECT ANSWER-
Unequal variance
A scatterplot that appears as a shapeless mass of data points
indicates: - THE CORRECT ANSWER-No relationship among the
variables.
Correlation is a summary measure that indicates: - THE CORRECT
ANSWER-The strength of the linear relationship between pairs of
variables.
A correlation value of zero indicates: - THE CORRECT ANSWER-No
linear relationship.
The correlation value ranges from - THE CORRECT ANSWER--1 to +1
The weakness of scatterplots is that they: - THE CORRECT ANSWER-Do
not actually quantify the relationships between variables.
