Variability in categorical variables while reducing dimensionality

by Feyzi Bagirov   Last Updated October 11, 2018 04:19 AM

If a dataset has a variable with categorical values (A, B, C, D, E, F), would converting them to numeric and breaking them down into separate columns (for example, column A that will have 1s for all occurrences of A and 0s for non-occurrences), would that affect variability?

If yes, how would a problem like that can be handled? (assuming conversion to numeric values and standardization has been done)
