Frequently Asked Questions
What is the difference between raw data and classified data?
Raw data is unorganized data collected directly from the field, whereas classified data is systematically grouped into categories and classes for easy understanding and analysis.
How do we convert an inclusive series into an exclusive series?
Find the difference between the upper limit of one class and the lower limit of the next class, divide it by 2, subtract this value from all lower limits, and add it to all upper limits.
Why is the organisation of data important in statistics?
It saves time, eliminates confusion, highlights essential features of the data, and makes comparison and further statistical analysis much easier.
