In mathematics, the mean is a measure of central tendency. The mean is calculated by adding up all the values in a set and dividing that total by the number of items in the set. The mean is often called the “average” or “middle” value because it is located in the middle of the distribution of data.The median is another important measure of central tendency. The median is calculated by taking the middle value in a set of data and dividing it by two. This makes it easier to see which values are more common than others. The median is often called the “middle” value because it is located in the middle of the distribution of data. All of these concepts are a part of the ICSE Class 9 Mathematics Revision Notes Chapter 19
In the first section of the course, the students will be introduced to the concept of mean, and how it is calculated for ungrouped data and what it means. The students will then have the opportunity to dig deeper and study how Mean is affected by the properties of any number, namely any number and how it increases or decreases the Mean depending on how it is being used, and how it is used. The first half of the chapter has come to an end with this conclusion. Every concept in the first half of the chapter can be revised by the students with the help of ICSE Class 9 Mathematics Revision Notes Chapter 19.
