For example, say the weight of students in a particular school. Also, remember that the mode is the most common score and especially remember to array scores from high to low before finding the median.) Distribution of statistical data shows how often the values in the data set occur. The range is often considered a measure of central tendency as well. That is, if scores are arranged in an ordered array from say highest to lowest or vice versa, the median would be the middle score.
