In statistics, a measure of central tendency is a single value or number that attempts to describe or represent a set of data by identifying the central position within that set of data. We are able to use a single value or number that attempts to describe or represent a set of data because most data tend to cluster around central points. For example: It would be difficult to tell how a class performed by looking at a long list of hundred scores. On the other hand, by applying the measures of central tendency — the mean, median or mode, we could get a typical or single number which would give us a better idea of the students performance. It would also help us compare this class with other classes. The average is another term for the mean — a measure of central tendency. Measures of central tendency are sometimes called measures of central location.

Disadvantages · It does not take into account the precise value of each observation and hence does not use all information available in the data. · Unlike mean.

## Measures of central tendency: Median and mode

Mean is typically the best measure of central tendency because it takes all values into account. Note that Mean can only be defined on interval and ratio level of measurement. Median is the mid point of data when it is arranged in order. It is typically when the data set has extreme values or is skewed in some direction. Note that median is defined on ordinal, interval and ratio level of measurement.

Apart from the mean, median and mode are the two commonly used measures of central tendency. The median is sometimes referred to as a measure of location as it tells us where the data are. It divides the frequency distribution exactly into two halves. Fifty percent of observations in a distribution have scores at or below the median.

The mode is the number, or item, which occurs most often in a set of data. To find the mode, find the value that occurs most. The mass of 7 babies are as follows:.

Arithmetic average, or arithmetic mean , or just mean , is probably the simplest tool in statistics, designed to measure central tendency in a data set which can be a group of stocks or returns of a stock in particular years. Using arithmetic average has advantages and disadvantages, and in some cases you may find other measures like geometric average or median more suitable. On this page:.
