\nWhile preparing a frequency distribution from the raw data, name the questions we have to address. Briefly explain in 1\u00bd pages. (March 2017)<\/span>
\n(Hint: Four steps in the construction of a frequency distribution)
\nAnswer:
\nWhile preparing a frequency distribution the following four points need to be taken into account<\/p>\n\n
\nThe first problem is the decision regarding the number of classes into which the raw data are to be classified. In order to avoid difficulties, we have to find out their range. The range is the difference between the largest and the smallest values of the variable.<\/p>\n
\nWe can determine the class interval once we decide on the number of classes. Thus these two decisions are interlinked with one another.<\/p>\n
\nThe choice of class limits is important in forming frequency distribution. There are two methods for the construction of a frequency distribution. They are<\/p>\n\n
\nIn order to ensure the continuity of variables, we can change the inclusive classes into exclusive classes. For this, find the difference between the lower limit of the second class and the upper limit of the first class. Divide the difference obtained by two.<\/p>\nPlus One Economics Chapter Wise Previous Questions and Answer<\/a><\/h4>\n","protected":false},"excerpt":{"rendered":"
