What are three common measures of central tendency?
There are three main measures of central tendency: the mode, the median and the mean. Each of these measures describes a different indication of the typical or central value in the distribution. What is the mode? The mode is the most commonly occurring value in a distribution.
What is mean, median and mode?
To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value in the data set occurs most often.
What is a measure of central tendency quizlet psychology?

What measure of central tendency best describes the center?
Since the data set is not skewed, the central tendency that best describes the “center” of the distribution is the mean. The arithmetic mean of a variable is computed by adding all the values of the variable in the data set and dividing by the number of observations.
What is central tendency?
Central tendency refers to the middle of a data set or where the scores in a data set tend to fall. There are three measures of central tendency; these tell us the average score (mean), the middle of the score range (median), and the most frequent score (mode). Together, these measures provide a good overall snapshot of the data.
