In our previous year, we learnt the classification of data into grouped and ungrouped frequency distribution. And, also learnt the representation of data in pictorial form.
In this chapter, we shall learn the procedure of solving the measures of central tendency of grouped data and the concept of cumulative frequency distribution.
The measures of central tendency is the value that tends to cluster around the middle value of the given set of data.
Measures of central tendency generally provide data or facts about average values of data in the given set.
The commonly used measures of central tendency are:
- Mean (or average)
- Median
- Mode
Each of the measures of central tendency can be determined using different methods. When the average data is applied to the original set of data, they often result in various average values. Hence, it is very important to understand which measure to find the average of the given data.
We shall learn about the various methods of solving the given data using the measures of central tendency in the upcoming topics.
