A nurse researcher is analyzing data from a survey that includes questions about pain levels, medication use, and functional limitations. The researcher wants to explore the relationship between pain levels and medication use. Which of the following statistical tests would be most appropriate?
Understand the Problem
The question is asking which statistical test is suitable for analyzing the relationship between two specific variables: pain levels and medication use from survey data. The approach will involve identifying the types of data involved and the appropriate statistical methods for analyzing them.
Answer
Chi-square test or logistic regression.
The most appropriate statistical test to explore the relationship between pain levels (a continuous variable) and medication use (often a categorical variable if grouped by type or frequency) would be the chi-square test if both variables are categorical, or a logistic regression if pain levels are continuous and medication use is binary.

The most appropriate statistical test to explore the relationship between pain levels (a continuous variable) and medication use (often a categorical variable if grouped by type or frequency) would be the chi-square test if both variables are categorical, or a logistic regression if pain levels are continuous and medication use is binary.
More Information
Chi-square tests are commonly used for assessing the association between two categorical variables, whereas logistic regression is used when the dependent variable is binary and predictors could be categorical or continuous.
Tips
Ensure the correct variable type is identified—whether continuous or categorical—to choose the correct statistical test.
