why is the density curve different when plotting two sets of data? why are density curves different why does density curves appear differently why do the two graphs look different what gives different results to density plots? different types of density curves when to use sm.density to plot density why is the density curve different what makes a density curve different why do two density curves appear similar why does density plot look different why do density curves look different why does my density curve look different how do you plot density in the same way how does density plot work what makes density curves different what makes two curves look different why does density look different? what makes density curve different how do you plot density
