Bivariate statistical measures regression and correlation

Bivariate statistical measures regression and correlation

1. regression analysis

   • gives rise to a mathematical equation that describes the existing relationship between two variables

2. Regression line

   • describes the relationship or dependency between two variables

3. covariance

   • it is a measure of dispersion, unlike the variances that always give positive results, this can be negative or positive

4. Correlation

   • It measures the strength of association between two variables.

5. bivariate measures of statistics

   • Multiple regression
   • Simple linear regression
   • correlation
   • Regression
   • Dispersion diagram

6. variance

   • is a measure that allows us to calculate the degree of dispersion of those values ​​that were explained by the regression line

7. Linear correlation coefficient

   • It is a regression measure that aims to quantify the degree of joint variation between two variables, it is responsible for indicating what is good and what is bad in the dot diagram
