A. In the Class 10 Maths Chapter 14 named Statistics, the students will be introduced to various interesting topics and sub-topics such as cumulative frequency tables, graphical representations of data/ bar charts, histograms, and frequency polygons. Sometimes, we need to describe the data arithmetically, like describing the mean age of a class of students, mean height of a group of students, median score or model shoe size of a group. In this chapter, students will be introduced to three measures of central tendency i.e., mean, median, mode of ungrouped data and mean of grouped data.
14.2: Mean of Grouped Data
14.3: Mode of Grouped Data
14.4: Median of Grouped Data
14.5: Graphical Representation Of Cumulative Frequency Distribution
