|
Area principle
|
A principle that helps to interpret statistical information without distortion by insisting that in a statistical display, each data value be represented by the same amount of area
|
|
|
Bar chart (relative frequency bar chart)
|
A chart that represents the count (or percentage) of each category in a categorical variable as a bar, allowing easy visual comparisons across categories
|
|
|
Column percent
|
The proportion of each column contained in the cell of a frequency table
|
|
|
Conditional distribution
|
The distribution of a variable restricting the Who to consider only a smaller group of individuals
|
|
|
Contingency table
|
Displays counts and sometimes percentages of individuals falling into named categories on two or more variables. The table categorizes the individuals on all variables at once, to reveal possible patterns in one variable that may be contingent on the category of the other
|
|
|
Distribution
|
Is a list of:
--all the possible values of the variable --the relative frequency of each value |
|
|
Frequency table (relative)
|
A table that lists the categories in a categorical variable and gives the number (the percentage) of observations for each category. The row percent is the proportion of each row contained in the cell of a frequency table, while the column percent is the proportion of each column contained in the cell of a frequency table
|
|
|
Independent variables
|
Variables for which the conditional distribution of one variable is the same for each category of the other
|
|
|
Marginal distribution
|
In a contingency table, the distribution of either variable alone. The counts or percentages are the totals found in the margins (usually the right-most column or bottom row) of the table
|
|
|
Pie chart
|
Pie charts show how a "whole" divides into categories by showing a wedge of a circle whose area corresponds to the proportion in each category
|
|
|
Row percent
|
The proportion of each row contained in the cell of a frequency table
|
|
|
Simpson's paradox
|
A phenomenon that arises when averages, or percentages, are taken across different groups, and these group averages appear to contradict the overall averages
|
|
|
Total percent
|
The proportion of the total contained in the cell of a frequency table
