### Measures of Central Tendency

1. Firstly, the NCERT Solutions For Class 11 Statistics Chapter 5 aim to present available measures of central tendency in statistics as students learn how to collect and present data. Next is data analysis and interpretation. To analyse the data, we use three different measures of central tendencies, such as the arithmetic mean, median, and mode.
2. Arithmetic mean
3. The arithmetic mean is a widely used measure for calculating the average of given data. Class 11 Statistics Chapter 5, also discusses two different variations called the mean for clustered data and the mean for unclustered data. The arithmetic mean for each method is the sum of all observations divided by the number of observations. A formula can represent it, and the student can calculate the average of the given data.
4. NCERT Solutions For Class 11 Statistics Chapter 5, Measures of Central Tendency, specifies that there are three different types of methods for calculating the average of scattered and clustered data. These are the direct method, the hypothetical method, and the step division method. Each method may differ for clustered and non-clustered data.
5. In NCERT Solutions For Class 11 Statistics Chapter 5, the answers are well explained with illustrations available on the website of Extramarks.
6. Median
7.  In this section, students are encouraged to study the median, another measure of central tendency. NCERT Solutions For Class 11 Statistics Chapter 5 explains that the median is a simple concept.It is calculated by taking the mean of the two sides of an equal value. However, this is only possible if the size of the series is odd. If a student is asked to find the median of a series of even values, in the middle he takes two terms and they must find the mean of the two terms.
8. Quadrants are another topic that is explained to students. If the total size is divided into four equal parts, then it is called a quarter. It can be calculated separately for two strings.
9. Percent is a topic where the whole size is broken down into 99 parts, reaching into the hundreds.
10. Fashion
11.  The NCERT Solutions For Class 11 Statistics Chapter 5, help students understand each measure of central tendency. Because if students grasp the meaning and formula, it is difficult to forget. Although the mode is the ultimate measure of central tendency, it has many meanings. Mode is a French word that means a fashion value or a value that frequently appears in a set. In a word, it can be said that mode is the value with the highest number of occurrences. For the direct method, students can calculate it directly by checking the website. For the continuous method, there is a specific formula for the mode value.
12. Relative positions of mean, median, and mode in the NCERT Solutions For Class 11 Statistics Chapter 5 also explains to students the location of the three measures of central tendency. If we can wave the triple-magnitude measures in any direction, the moving average should be in the middle. The mode and the mean will be in one of the extreme positions.
13. End
14. Thus, in chapter 5 measures of central tendency have been carefully explained to students by specialist teachers. NCERT Solutions For Class 11 Statistics Chapter 5 provides various examples of the six concepts.
