CBSE Class 10 Maths Chapter 14 Statistics

In Class IX, you have studied the classification of given data into ungrouped as well as grouped frequency distributions. You have also learned to represent the data pictorially in the form of various graphs such as bar graphs, histograms (including those of varying widths), and frequency polygons. In fact, you went a step further by studying certain numerical representatives of the ungrouped data, also called measures of central tendency, namely, mean, median, and mode.

In this chapter, we shall extend the study of these three measures, i.e., mean, median, and mode from ungrouped data to that of grouped data. We shall also discuss the concept of cumulative frequency, the cumulative frequency distribution, and how to draw cumulative frequency curves, called ogives.

where l = lower limit of the modal class,

h = size of the class interval (assuming all class sizes to be equal),

f₁ = frequency of the modal class,

f₀= frequency of the class preceding the modal class,

f₂= frequency of the class succeeding the modal class.
