A researcher collects two samples of people: people who vote regularly and people who never vote. They then randomly assign people in both samples to read a passage about a political issue. Some people are randomly assigned to read a passage that is merely factual. Other people are randomly assigned to read a passage with a great deal of invective and hostility. The researcher wants to know if people's response to the passage's level of civility will depend on whether the person votes regularly or not. What is the method the researcher will use to test their hypothesis?
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
