Heres how your frequency distribution table might look: The mode and the median are measures of central tendency (the other possible measure of central tendency is the mean, but this doesnt apply to ordinal data). In the interval level of measurement, the variables are still classified into orderedcategories, but there is an equivalent distance between these categories. In a physics study, color is quantified by wavelength, so color would be considered a ratio variable.
