Statistics is defined as the ‘science of data’, which deals with collection, classification, summarization, organization and analysis of data, interpretation of numerical and categorical data, along with inferring about the nature of the data.

The researcher uses statistics (mean) to find the average heights of the students, infer about the heights of 7^th grade students in general, and makes a conclusion.
