For the following research questions indicate the PREDICTOR variable and the OUTCOME variable. 1.Are there differences in the amount of discipline referrals between girls and boys with Autism SpectrumDisorders? Outcome variable: Predictor (grouping) variable: b. Do students exposed to animated science materials learn more if the animation is accompanied by soundor no sound? Outcome variable: Predictor (grouping) variable: c. The goal of this study was to compare scores on a standardized achievement test in classes using atraditional mathematics textbook and classes using a reform mathematics curriculum emphasizingmanipulatives. Outcome variable: Predictor (grouping) variable: d. What variable best predicts whether first generation college students stay continually enrolled in collegeuntil graduation? Outcome variable: Predictor (grouping) variable:
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.
