*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.*

*Apart from the mean, median and mode are the two commonly used measures of central tendency.*

A measure of central tendency is a value that is typical of a data set. Any measure of central tendency is considered to be representative of a whole data set or distribution; so by itself, it provides a description or summary of the data set as a whole. A conceptual understanding of measures of central tendency is basic to understand many aspects of educational measurement and thus essential for inclusion in this resource book.

## Measures of Location and Dispersion and their appropriate uses

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.

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:. There is only one value that occurs twice, which is 3. All other items occur only once.

Measures of location describe the central tendency of the data. They include the mean, median and mode. Their calculation is described in example 1, below. The median is defined as the middle point of the ordered data. It is estimated by first ordering the data from smallest to largest, and then counting upwards for half the observations. The estimate of the median is either the observation at the centre of the ordering in the case of an odd number of observations, or the simple average of the middle two observations if the total number of observations is even. The mean is defined as the sum of the observations divided by the number of observations.

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.

По приезде группу сразу же разделили. Все они подверглись проверке на полиграф-машине, иными словами - на детекторе лжи: были тщательно проверены их родственники, изучены особенности почерка, и с каждым провели множество собеседований на всевозможные темы, включая сексуальную ориентацию и соответствующие предпочтения. Когда интервьюер спросил у Сьюзан, не занималась ли она сексом с животными, она с трудом удержалась, чтобы не выбежать из кабинета, но, так или иначе, верх взяли любопытство, перспектива работы на самом острие теории кодирования, возможность попасть во Дворец головоломок и стать членом наиболее секретного клуба в мире - Агентства национальной безопасности. Беккер внимательно слушал ее рассказ.

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.

The major types of central tendency are the mean, median and mode. In statistics, a measure of central tendency is a single value or number that attempts the advantages and disadvantages of the different measures of central tendency.
