Statistical Measures Bivariante

1. Analyis Models

2. Allows to analyze two variables to identify the relationship between them

3. Analyis Models

   • Deterministic
     • Dicloses the value of the dependent variable
   • Statistical
     • Prediction error
   • Standarized
     • Relationship between two variables

4. Regression

   • Is used to derive equation
     • simple regression analysis
       • A single variable
     • multiple regression analysis
       • two or more variables

5. linear regression

   • analyzes behavior and determines whether it is dependent or exogenous
   • Simple
     • represents the straight line in the plane
   • coefficient of linear determination
     • Represents the Y dependency on X

6. Correlacion

   • Tipos
     • direct correlation
       • results in a growing straight
     • inverse correlation
     • zero correlation
       • no relation between the variables
   • identifies the force and direction

7. Degrees

   • strong correlation
     • the points are very close
   • debit correlation
     • much dispersion
   • zero correlation
     • positive correlation
