A ________ allows a researcher to visually inspect the plotted points and possibly to spot a systematic nonlinear relationship.
multiple line graph
stacked bar chart
line graph
scatter plot
scatter plot
A ________ describes the situation in which knowledge of the amount of one variable will automatically yield knowledge of the amount of the other variable as a consequence.
monotonic relationship
linear relationship
curvilinear relationship
nonmonotonic relationship
linear relationship
A cross-tabulation table is sometimes referred to as a(n):
r × c table.
c × x table.
t × n table.
z x t table.
r × c table.
A handy graphical tool that illustrates a nonmonotonic relationship is a ________ in which two variables are accommodated simultaneously.
horizontal bar chart
stacked bar chart
grouped bar chart
pie chart
stacked bar chart
A relationship which is described as one in which there is a low probability that two variables will exhibit a dependable relationship is referred to as:
A strong association.
Weak probability.
A high degree of association.
A low degree of association.
A low degree of association.
An index number, constrained to fall between -1.0 and +1.0, that communicates both the strength and the direction of a linear relationship between two scale variables is a:
Standard deviation.
Correlation coefficient.
Standard error.
Covariant.
Correlation coefficient.
Any correlation that falls between the absolute value range of ________ is usually considered indicative of a “weak” association between the variables.
.21 and .40
1.00 and .81
.80 and .61
.60 and .41
.21 and .40
Any correlation that is ≤ absolute value of .20 is typically uninteresting to marketing researchers because it:
Only raises additional issues that go beyond the scope of the calculations.
Never identifies a meaningful association between two variables.
Raises issues related to validity and accuracy.
Rarely identifies a meaningful association between two variables.
Rarely identifies a meaningful association between two variables.
A ________ is one in which the presence (or absence) of a label for one variable is systematically associated with the presence (or absence) of a label for another variable.
non-elliptical relationship
non-curvilinear relationship
nonmonotonic relationship
non-linear relationship
nonmonotonic relationship
Correlation coefficients that fall between the absolute values of 1.00 and .81 are generally considered to be:
Very weak.
Somewhat weak.
Very strong.
Somewhat strong.
Very strong.
