# CBSE Class 9 Maths Statistics

CBSE Class 9 Maths Statistics is a crucial chapter in the Syllabus of CBSE Class 9 as it holds various data-related skills related to it. Students must know that statistics help present complex data in simple tabular forms. Statistics enables us to know various data patterns, which help study and analyse various measurable parameters like population and much more. Moreover, it also helps in the effective planning of statistical inquiry in any field of study, and hence it becomes essential for learners to study the concepts of Statistics. For example, CBSE Class 9 Maths Grouping and Tabulation of data helps learners understand the various grouping and tabulation methods of data sets and includes problem-solving videos on the cumulative frequency tables. Like-wise, CBSE Class 9 Maths Graphical Representation of Data shows various graphical means through which data sets can be presented like Frequency polygonsHistogramsCBSE Class 9 Maths Measures of Central Tendency lets learners know about methods to solve application-based problems on various statistical approaches like MeanMedian and Mode.

What is the meaning of statistics according to NCERT Solutions for Class 9 Maths Chapter 14?

Accordingly to NCERT Solutions for Class 9 Maths Chapter 14, Statistics deals with collecting, presenting, analysing, and interpreting data. Data can be either ungrouped or grouped. Further, grouped data could be categorised into:

(a) Discrete frequency distribution and (b) Continuous frequency distribution.

Data can be represented in tables or the form of graphs. Common graphical forms are bar charts, pie diagrams, histograms, frequency polygons, ogives, etc.

The first order of comparison for a given data is the measures of central tendencies. Commonly used measures are (i) Arithmetic mean (ii) Median (iii) Mode.

How can we find the median of grouped data?

Median is the measure that divides the data into two equal parts. The median is the middle term when the data is sorted. In the case of odd observations, the middle observation is the median. In the case of actual observations, the median is the average of the two middle observations. The median can be determined graphically. It does not take into account all the observations.
