A statistical method thar allows us to summarize and study the linear relationship between two quantitative variables. That best fit for the data points
SIMPLE LINEAR REGRESSION
A measures the strength of the relationship between the two variables
CORELLATION COFFIECIENT
This are used for comparing a sample that more than two populations, data experiments that have more than two treatments tha have been used
ANOVA
This is the attempts to model the relationship between two or more explanatory variables and a response variable by fitting linear equation to observe a data. Also an extension of the simple linear regression model. It was a powerful techniques that used to predict te unknown variable.
