b. According to the guidelines published by Cohen (1988), a correlation value of –0.60 would be considered ___. Group of answer choices medium large small c. Which of these is NOT an assumption when conducting hypothesis testing for r? Group of answer choices To insure generalizability, the data should be randomly selected. The population distributions should be normal. The variables being studied are positively correlated. The variability of scores on one variable should be equal across all levels of the second 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.
