When there are extreme scores or outliers in your distribution, the median is the preferred statistic to measure central tendency. It is simply the midpoint in your distribution of ranked, ordered scores. To calculate the median, list all of the values in your distribution from the lowest to the highest and then find the midpoint — the place where it divides your distribution into equal halves.
That is, fifty percent of all scores is above and fifty percent is below. If there is an odd number of scores in your distribution, the median is easy to identify. Find the midpoint in the range of high to low scores. That midpoint is the median, since half of the scores are above it and half are below it. A formula can be used to locate the position in an ordered set of data. The median would be the sixth score in the set of data where the scores are listed in order from lowest to highest.
If you have an even number of scores, find the two that make the centermost point, and then average them. If you have an even number of scores, the median may or may not be an actual score, depending on what the two midpoints are.
If the midpoints are identical scores, then this is the median. If they need to be averaged, then the median will be an average and not an actual score in your distribution. That is why we say the median is the midpoint, a point not a score. The mode is the most frequently occurring value in your distribution. The mode as a statistic does not need to be calculated. If you look at your frequency distribution, a simple eyeball inspection of your data can tell you which score occurred most often.
Many frequency distributions have more than one mode. The first chapter of the dissertation is the dissertation introduction.
