indicator variable aka dummy variables
An independent variable in a regression model that
interaction term
is the product of two explanatory variables.
interaction term is used how the synergies between multiple variables
to model impact the response variable
R2 will always never you add more parameters

the mean of a variable FALSE
that has a right-skewed
distribution is smaller
than the median (T/F)
the correlation FALSE
coefficient can capture
the strength of both
