*It can be easily calculated; and can be easily understood. It is the reason that it is the most used measure of central tendency. Fluctuations are minimum for this measure of central tendency when repeated samples are taken from one and the same population.*

MEAN The arithmetic mean or simply "mean" of a sample is the sum of the sampled va lues divided by the number of items in the sample. Merits of median 1 Simplicity:- It is very simple measure of the central tendency of the series.

I the case of simple statistical series, just a glance at the data is enough t o locate the median value. Median values are al ways a certain specific value in the series. Demerits of median: Following are the various demerits of median: 1 Lack of representative character: - Median fails to be a representative meas ure in case of such series the different values of which are wide apart from eac h other. Also, median is of limited representative character as it is not based on all the items in the series.

For example, multiplying the median with the nu mber of items in the series will not give us the sum total of the values of the series. However, median is quite a simple method finding an average of a series. It is q uite a commonly used measure in the case of such series which are related to qua litative observation as and health of the student. Mode: The value of the variable which occurs most frequently in a distribution is call ed the mode.

Merits of mode: Following are the various merits of mode: 1 Simple and popular: - Mode is very simple measure of central tendency. Somet imes, just at the series is enough to locate the model value. Because of its sim plicity, it s a very popular measure of the central tendency. Mode is determined only by the value with highe st frequencies. Accordingly, mode is the best representative value of the series.

In simple series, it is enough if one knows the items with highest frequencies in the distribution. Demerits of mode: Following are the various demerits of mode: 1 Uncertain and vague: - Mode is an uncertain and vague measure of the central tendency. If the extent of grouping changes there will be a ch ange in the model value. To that extent model value is not a representative value of all the items in a series.

Besides, one can question the representative character of the model v alue as its calculation does not involve all items of the series. Related Papers. Std11 stat em. By NDY ekwere.

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:. As the most basic measure in statistics, arithmetic average is very easy to calculate. For a small data set, you can calculate the arithmetic mean quickly in your head or on a piece of paper. Here you can see the basics of arithmetic average calculation.

The arithmetic mean or simply "mean" of a sample is the sum of the sampled values divided by the number of items in the sample. The median is that value of the series which divides the group into two equal parts, one part comprising all values greater than the median value and the other part comprising all the values smaller than the median value. I the case of simple statistical series, just a glance at the data is enough to locate the median value.

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.

1) Arithmetic mean rigidly defined by Algebraic Formula. 2) It is easy to calculate and simple to understand. 3) It is based on all observations of the given data. 4) It is capable of being treated mathematically hence it is widely used in statistical analysis.
