A community health researcher is investigating the effects of stress on health on people in a high-crime neighborhood, and what may contribute as a stressor. A door-to-door survey is taken on many topics, including two Likert scale questions regarding the person's level of stress (none to very high, five point scale) and the level of which they approve of policing in their neighborhood (highly disapprove to highly approve, five point scale). What method would be appropriate to examine the association between a person's perceived stress and caliber of local police work?

Break the situation down into the components for choosing a statistical test:

• What is the dependent variable?
• What type is the dependent variable?
• What is (are) the independent variable(s)?
• What type(s) is (are) the independent variable(s)?
• What are other things that could affect the statistical analysis?
• Pick a statistic test from the following:

One-sample t-test

Paired t-test

Two-sample t-test

ANOVA

Chi-square test

Simple linear regression

General linear model

Logistic regression

Wilcoxon rank-sum test

Kruskal-Wallis test

Spearman correlation

Fisher's exact test

Log-rank test
