## Class 10 Chapter 9 Mean, Median and Mode - At A Glance

• The value that represents the whole set of data is known as a central tendency.

• The value of central tendency lies within the range of the data.

• The central tendency can be measured using three different approaches: Mean, Median and Mode.

• The Mean of the data is generally the average of the data that is calculated by dividing the sum of all values by the number of values in the data set.

• The Median in a dataset is generally the middle value of the dataset when it is arranged in ascending order or descending order.

• This value will divide the data into two halves.

• The formula for calculation of the Median value of the dataset depends upon if the dataset has even observations or odd observations.

• The Mode value represents the value or observation that occurs most frequently in the data set. The data sets in the question can even have more than one Mode value.

• Uni-modal datasets contain one Mode, bi-modal data sets contain two Modes and the tri-modal dataset contains three Modes.

• Bi-modal and trimodal datasets are also known as multimodal datasets.

• Range refers to the difference between the highest value and the lowest value present in the concerned data set.

### Tips for Performing Well in Questions Related to Chapter 9:

Chapter 9 is very important for students of Class 10 as they form a strong base for probability and statistics which is one of the most essential concepts for higher studies and competitive exams. Certain tips that can help students perform well in the questions related to this chapter are:

• Practice as many questions as you can.

• Learn formulae by heart.

• Revise your concepts every few days.

5. How can I solve question 2 of exercise 9A of RS Aggarwal Class 10?

Question 2 of Chapter 9 Class 10 RS Aggarwal provides the student with a Mean of 25 observations, that is 27 and the student needs to find out the new Mean if 7 is subtracted from the sum of observations. The Mean of the given observation is calculated by dividing the sum of given observations by the total number of observations. Thus, the student must first find out the sum of observations by using the above-mentioned formula and then deduct 7 from the sum of observations. Then the students can calculate the new Mean using the new sum of observations.
