Describe the advantages and disadvantages of the three measures of central tendency: mean, median, mode.
What will be an ideal response?
The mean is the most commonly used measure of central tendency. Because it is affected by a change in any score, the mean can be seriously affected by extreme values. The median is the middle point in the frequency distribution, above which half the scores fall and below which half the scores fall. The median, because it is based on the frequency of scores and not the value of scores, is appropriate when there are extreme values in the distribution. The mode is the score appearing most frequently in the distribution. It is the simplest to calculate but is often the least useful of the measures of central tendency.
