Exam 12: Bivariate Association: Introduction and Basic Concepts

A researcher tested the relationship between education and support for assisted suicide ("death with dignity")and found that support increased as education increased and that the maximum difference was 45.This relationship is

The distribution of scores on the dependent variable for a specific category of the independent variable is called

The closer the value of a measure of association is to one,

If there is an association between two variables,

If there is a perfect association between sexual attraction and accelerated heartbeat,then

The table below displays the effects of hair color on political ideology for a sample.How should this relationship be characterized? Hair Color Blonde Not Blonde Libera 60\% 60\% Conservative 40\% 40\% 100\% 100\%

If the conditional distributions of Y do not change across the categories of X,any measure of association and the maximum difference would be

In the case of a perfect association,predictions from one variable to another can be made

If the conditional distributions of Y change,the variables are

Measures of association provide the researcher with information that

Tests of significance tell us if our results are non-random.To investigate the strength and direction of relationships,we must use

A state is considering legislation to establish a fifteen day waiting period for the purchase of hand guns.A sample of 392 citizens has been questioned regarding their opinions.Is there a relationship between sex and support for this law? Calculate percentages for the table below and write a sentence or two assessing the strength and pattern or direction of the relationship. Sex Male Female Support For 113 145 258 Against 78 56 134 191 201 392

A researcher finds that males are much more supportive of cohabitation than females.The maximum difference is 25.This is a ____ relationship.

To prove that one variable causes another,we use

Is there an association between support for the legalization of marijuana and age? Calculate percentages for the table below and write a sentence or two assessing the strength and pattern or direction of the relationship. Age Less than 35 35-50 50 andOlder Suppat In Favor: 36 23 17 76 Neutral 20 17 16 53 Opposed 10 18 36 64 66 58 69 193

In a bivariate table,the categories of the dependent variable are placed in the

One way to detect an association between variables is the chi square statistic.Variables are associated if obtained chi square is

With the independent variable in the columns,the "maximum difference" is the largest difference

A maximum difference greater than 30 would usually be accompanied by a ____ measure of association.

If the distribution of the scores of one variable changes across the categories of another variable,the variables
