When working on a given set of data, it is not possible to remember all the values in that set. But we require inference of the data given to us. This problem is solved by mean median and mode. These, known as measures of central tendency, represent all the values of the data. As a result, they help us to draw an inference and an estimate of all the values. Let us learn about the measures of central tendency and the calculation of Mean Median and Mode.
The Measures of Central Tendency – Mean Median and Mode
As already discussed, the mean median and mode are known as measures of central tendency. They are also known as statistical averages. Their simple function is to mathematically represent all the values in a particular set of data. Hence, this representation shows the general trend and inclination of all the values.
Mean Median and Mode
An average provides a simple way of representation of all the individual data. It also aids in the comparison of different groups of data. In addition to this, an average in economic terms can represent the direction an economy is headed towards. Hence, it can be easily used to formulate policies and bring about a reform for a better economy.
For example, a low per capita income is an indication for the government to formulate policies focused on the increase in income of people. We will learn about three measures of central tendency- Mean Median and Mode.
