1.	What is frequency distribution? What are the main points underlying the construction of a frequency distribution?
Answer» In statistics, a frequency distribution is a list, table or graph that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval. The main general guidelines for the contraction of a frequency distribution are :(i) All class intervals should be of equal size(ii) The lower limit of the first class should either be 0.5 or multiple of 5.(iii) We should avoid odd sized class interval(iv) Open-end classes should be avoided
