That data which is shown in the video includes more than one variable to be non-metric/categorical. Can we still use multiple regression for the same? Are dummy variables (for 'k' categories of each independent variable, 'k-1' dummy variables) used to calculate the regression equation? My understanding was to use ANCOVA for such cases. Please clarify.

Mam, it is very difficult to hear your videos.
