Question

"The loss of information can be minimized but cannot be completely avoided in arranging the data in a frequency distribution." Justify the statement.​

Answer 1

The missing information or missing class interval in a frequency distribution of a data set cannot be completely avoided but however can be minimized by adopting various effective data collection methods.

Explanation:

In Statistics,much of the data collection and information gathering require practical effort,time and immense monetary resources.Especially,in the context of any study topic related to social science,selection of sample accurately and data collection from the sample often warrant extensive and time consuming methods and procedures.Therefore,sometimes collecting the data and arranging them according to their frequency distribution becomes difficult.In the case of small data,however it might be possible to avoid missing information but for most cases,in a practical sense,it cannot be avoided or even minimized given the practical constraints related to the whole process of sample selection and data collection.
