a consistent and systematic linkage between the levels or lavels for two variables.
|
relationship
|
|
two variables are shown simultaneously in the same bar graph. each bar stands for 100%
|
stacked bar chart
|
|
the analytical technique that assesses the statistical significance of Boolean or categorical varible relationships is
|
cross tabulation analysis
|
|
contains the raw counts of the various boolean relationships found in the complete data set.
|
frequencies table
|
|
an index number, constrained to fall between the range of -1.0 and +1.0, that communicates both the strength and the direction of the linear relationship between two metric variables
|
correlation coefficient
|
|
correlation coefficient's deal with what type of variables?
|
metric
|
|
correlation coefficient indicates the degree of -------- between two variables
|
covariation
|
|
defined as the amount of change in one variable systematically associated with a chang in another variable.
|
covaration
|
|
the greater the absolute size of the correlation coefficient, the greater is the -------------------------, or the stronger is their relationship regardless of sign
|
covariation between two variables
|
|
used to illustrate covariation. plots data pairs in an x and y axis graph
|
scatter diagram
|
|
the variable that is predicted and is customarily termed y in the regression straight-line equation.
|
dependent variable
|
|
the one that is used to predict the dependent variable, that is the x in the regression formula.
|
independent variable
|
|
What methods of doing business are associated with level of customer satisfaction?
What demographic variables are associated with repeat buying of Brand A? Is type of sales training associated with sales performance of sales representatives? Are purchase intention scores of a new product associated with actual sales of the product? |
examples of relationships
|
|
describe each unit of the property being measured.
|
descriptors
|
|
When the scale is metric, descriptors measure ----- of the property – levels of temperature, levels of satisfaction, etc.
|
levels
|
|
When the scale is categorical, the descriptors measure ------ of the properties – buyer versus non-buyer; yes, no; etc.
|
labels
|
|
is a consistent and systematic linkage between the levels (for metric scales variables) or labels (for categorical scaled variables) for two variables.
|
a relationship
|
|
Knowledge of relationships between variables can give marketers -------- ------- into phenomena in the marketplace.
|
advantageous insights
|
|
is the analytical technique that assesses the statistical significance of Boolean or categorical variable relationships.
|
A cross-tabulation analysis
|
|
the two variables are arranged in a cross-tabulation table in a row-and-column format.
|
cross tabulation
|
|
is the intersection of a row and a column.
|
a cross tabulation cell
