Think of some "scores" that have been important to you in your life. Describe one personal score for each type of measurement scale (nominal, ordinal, interval, and ratio). Second, state which measure of central tendency (mean, median, or mode) is appropriate given the measurement scale. Recall that interval and ratio data differ in the best measure of central tendency depending on whether the dataset is normally distributed or skewed. For example, income as a variable is a skewed distribution.
