Your professor is interested in determining if mode of presentation affects how prose material is remembered. She used one prose passage that was presented visually and auditorily. From 200 undergraduate students in the university, only 10agreed to participate. On the first day of the experiment, the 10participants receives visual presentation of the prose passage while on the second day, same participants hears the passages through an auditory presentation. At the end of each presentations, participants were asked to say as much of the material as they can remember within 2 minutes. The words remembered were obtained.

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.
