Regression and correlation
Statistical technique used to derive an equation that relates a criterion variable to one or more predictor variables
BIVARIANT STATISTICAL MEASURES
multiple regression
Study the relationship between two quantitative variables
Dispersion diagram
simple linear regression
REGRESSION ANALYSIS
It studies the strength of the association through a measure of association called the correlation coefficient.
BIVARIANT STATISTICAL MEASURES OF REGRESSION AND CORRELATION
The regression can be linear and curvilinear or nonlinear, they can be
The regression coefficient can be: positive, negative and null
MULTIPLE REGRESSION
regression coefficient
Determine the degree of correlation between the variables, the coefficient of determination also called R square reflects the goodness of the adjustment of a model to the variable.
