Quizplus · Accepted Answer

The mean is a measure of central tendency that is best suited to interval or ratio level data that form approximately normal distributions. These are the types of data that are most commonly used in behavioral research. As such, the mean is frequently used in psychological research because it provides a useful summary of the typical score in a particular data set. Other measures of central tendency, such as the mode, are less commonly used in psychological research because they do not provide as informative a summary of the data.
