Question

(w) list five reasons for organizing data into a frequency distribution?

Answer 1

Following are the five reasons for organizing data into a frequency distribution:

1. When raw data is organized in the form of frequency distribution then it can be easy to understand data. For example: if frequency of a class 10 - 19 is 15 then we can say clearly that 15 data are in the range of 10 to 19. But it is not easy to answer it by visualizing raw data.
2. We can predict the shape of distribution of data with help of frequency distribution. For example: if frequency starts from low to maximum then it will be negatively skewed shape or left skewed shape.
3. We can use statistical tools when data is organized in a frequency distribution.
4. We can plot the graph like histogram or bar chart if data is converted as frequency distribution with help of excel or other statistical tools.
5. We can compare two or more data sets with each other with help of frequency distribution by keeping class interval same.
