Regression analysis is used to model the relationship between variables. There are different types including simple linear regression with one independent variable, multiple linear regression with multiple independent variables, and logistic regression for nominal dependent variables. To calculate a regression online in 3 steps, you copy your data into a statistics calculator, select the dependent and independent variables, and calculate the regression.

3. Regression analysis is used to create a model that describes the
relationship between a dependent variable and one or more
independent variables.
Weight = b0 + b1 ∙ Size + b2 ∙ Age + b3 ∙ Gender

4. What do I get out of this model???
With the model:
▪ the dependent variable is
predicted by the independent
variables
▪ the dependence of the dependent
variable on the independent
variables is determined
Beispiel:
▪ How heavy is a person who is 1.85
tall, 33 years old and male?
▪ What does the weight of a person
depend on most?
