NCERT solutions for class 10 maths chapter 13 ex 13.3 Statistics is concerned with the concept of the median of a grouped data. Students must already understand that the median is a measure of central tendency which gives the value of the middle-most observation in the data. To figure out the median, you first need to arrange the data in ascending order.
Ex 13.3 of NCERT solutions class 10 maths chapter 13 will help the students study all three measures of the central tendency and see if there's an empirical connection between them. The three measures are the mean, median and mode.

Topics Covered in Exercise 13.3 Class 10 Mathematics Questions
NCERT solutions class 10 maths ex 13.3 covers questions related to the topic median of grouped data.
Median of Grouped Data
Median of Grouped Data - If we put the numbers in ascending or descending order, then the middle number in the series will be the median. If number of series is even then the median is the average of the two middle numbers.
If n is odd, the median is the (n + 1 / 2)th observation.
if n is even, then the median will be the average of the n/ 2th and the (n/2 + 1)th observations
There is a empirical relationship between the three measures of central tendency :
3 Median = Mode + 2 Mean
