# CBSE Class 10 Maths Statistics

Statistics chapter in CBSE Class 10 Maths deals with mean, frequency, class interval, grouped and ungrouped data, finding the mean for grouped data when class intervals are given, finding the mean for grouped data when class intervals are not provided, direct method of finding mean, assumed mean method of finding mean and much more. After students complete the entire chapter of the CBSE Class 10 Maths, they will do a quick statistical analysis of a large amount of data in real-life situations. Moreover, students will also be able to collect, represent and classify data of any kind to ease the understanding while doing calculations.

Mathematics is the most crucial subject in an aspirant's school life. Therefore, board exam aspirants must practice CBSE Class 10 Maths based on the latest syllabus of CBSE Class 10. There are 15 chapters in the Mathematics syllabus of CBSE Class 10: Real Numbers, Quadratic Equations, Arithmetic Equations, Circles, Constructions, Area Related to Circles, Polynomials, Statistics, Probability, and more. These Mathematics CBSE Class 10 chapters include all the fundamental concepts every student should be acquainted with.

#### Arithmetic Mean of Grouped Data

Calculate arithmetic mean of grouped data by using three different methods. Direct, short cut, step deviation method#### Mode of Grouped Data

The mode of data is the observation that occurs most often. If all the observations are occurring only once, mode is not defined.

The mode may be greater than, less than or even equal to the mean.

Mode is useful in market research.

The mode may be greater than, less than or even equal to the mean.

Mode is useful in market research.#### Median of Grouped Data

For finding the median we must arrange the given data in increasing or decreasing order.

The frequencies obtained by adding frequency of a class with the sum of frequencies of the preceding classes is called cumulative frequency.#### Relation Between Central Tendencies

A distribution in which the values of mean, median and mode coincide(i.e. mean = median = mode) is known assymmetrical distribution.

Distribution for which values of mean, median and mode are not equal is known as asymmetrical or skewed distribution.

Empirical formula for moderately asymmetric distributions is given by Median = Mode + 2 mean.#### Cumulative Frequency Curve

A cumulative frequency distribution is represented graphically by means of a curve called an 'ogive'.

Ogives are of two types- 'less than ogive' and 'more than ogive'

An ogive has the lower/upper limits plotted on the x axis and the cumulative frequency on the y- axis. They are helpful in finding the value of median of the given data.

If a 'less than ogive' and 'more than ogive' for the same data are plotted on the same graph, then the x-coordinate of their point of intersection represents the median for the data.
