1. quantitative bivariate analysis

   • Linear function: linear regression, Y=a+bx
     • dependent variables (Y) Independent variables (x)
   • The joint distribution of two variables is expressed graphically by means of a scatter diagram.

2. Correlational analysis measures and indicates the degree to which n values ​​are related to one another.

3. Pearson correlation coefficient

   • is a statistical index that measures the linear relationship between two quantitative variables

4. linear regression

   • regression tries to explain the behavior of a variable called slope or endogen based on another variable
     • linear coefficient of determination
     • simple linear regression
     • regression analysis models
     • linear regression analysis
     • linear regression coefficient

5. linear correlation

   • establishes the relationship or dependency that exists between the two variables
     • correlation types
       • direct correlation
       • inverse correlation
       • null correlation
     • degree of correlation
       • strong correlation
       • weak correlation
       • null correlation
     • multiple regression
       • Regression can be linear and curvilinear or nonlinear
       • coefficient of determination R2
