A part of the Unit, Statistics and Probability; NCERT Grade 10 Mathematics Chapter 14, Statistics holds a total weightage of 11 marks in the final examination along with other chapters of the same unit.
In Class IX, students have studied the classification of given data into ungrouped as well as grouped frequency distributions. They have also learnt 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, the students 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, they shall extend the study of these three measures, i.e., mean, median and mode from ungrouped data to that of grouped data. Students shall also discuss the concept of cumulative frequency, the cumulative frequency distribution and how to draw cumulative frequency curves, called ogives.
Mean of Grouped Data, Mode of Grouped Data, Median of Grouped Data and Graphical Representation of Cumulative Frequency Distribution are some of the concepts learnt through NCERT Grade 10 Mathematics Chapter 14, Statistics. Graphical representation makes the chapter more interactive and clears the concepts in a better and comprehensive manner.
