Abstract: Abstract In the previous chapter, unimodal and bimodal score distributions were demonstrated. In addition to the mode or most frequent score in a sample of data, the mean and median are also considered measures of central tendency. Central tendency is where most scores occur in the middle of a symmetrical distribution and then spread out. The mode, mean, and median values will all be identical in a normal distribution.
