Transformation usually requires changing the scale of the variable so that we can use it with a particular statistical test. We can take the log of the variables if the residuals are not evenly spread across in a regression model. We can transform variables to create dummy variables or bins based on specified ranges. If we have a Likert scale variable, for example, we can transform it into a dummy variable with numerical values. Great question!
Hi, what is the symbol for division and why is multiplication a *?
The symbol for division is "/" and multiplication has typically been done with "*" across numerous computer programs over the years. Great questions!
why do we need to transform?
