Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. Examples include the sample mean. In this formula, MOE represents the desired margin of error (which you set ahead of time), and represents the population standard deviation. Where S = Standard deviation and is the square root of the variance. So before calculating median the data should be ordered either in ascending or descending order. It presents the data in an organized manner. Statistics is a branch of mathematics which deals with numbers and data analysis. What is Statistics in class 10 Maths?
