Question

briefly explain the 4 question to be addressed while preparing a frequency distribution

Answer 1

Statistics is a very useful subject that is originated from mathematics. Its study is started in middle school and becomes a separate subject in higher-level mathematics. Statistics is a systematic study of collection, organization and analysis of data for a research or a survey. It is quite helpful in the forecast and prediction of various results from the well-organized data.

A statistical data may consists of a list of numbers related to a research. Among those numbers, few may be repeated twice and even more than twice. The repetition of number is a data set is termed as frequency of that particular number or the variable in which that number is assigned. The frequencies of variables in a data are to be listed in a table. This table is known as frequency distribution table and the list is referred as frequency distribution.

This page includes the study of frequency distribution with various examples. Our study on frequency distribution includes a study on cumulative frequency, mean frequency table. Frequency distribution can be defined as the tabulation of the values with one or more variables. A frequency distribution is defined as an orderly arrangement of data classified according to the magnitude of the observations.

Answer 2

Answer:

While preparing frequency distribution, the following four questions need to be addressed:

a). How many classes should we have?

b). What should be the size of each class?

c). How should we determine the class limits?

d). How should we get the frequency for each class?
