Statistics Definition: Statistics is a branch that deals with every aspect of the data. Statistical knowledge helps to choose the proper method of collecting the data and employ those samples in the correct analysis process in order to effectively produce the results. In short, statistics is a crucial process which helps to make the decision based on the data.
What is Statistics in Maths?
In Mathematics, statistics concerns the collection of data, organisation, interpretation, analysis and data presentation. The main purpose of using statistics is to plan the collected data in terms of experimental designs and statistical surveys. Statistics is considered a mathematical science that works with numerical data. In short, statistics is a crucial process which helps to make the decision based on the data.
An example of statistical analysis is when we have to determine the number of people in a town who watch TV out of the total population in the town. The small group of people is called the sample here, which is taken from the population.
Types of Statistics
The two main branches of statistics are:
- Descriptive Statistics
- Inferential Statistics
Descriptive Statistics – Through graphs or tables, or numerical calculations, descriptive statistics uses the data to provide descriptions of the population.
Inferential Statistics – Based on the data sample taken from the population, inferential statistics makes the predictions and inferences.
Both types of statistics are equally employed in the field of statistical analysis. Learn in detail descriptive and inferential statistics here at BYJU’S.
Characteristics of Statistics
The important characteristics of Statistics are as follows:
- Statistics are numerically expressed.
- It has an aggregate of facts
- Data are collected in systematic order
- It should be comparable to each other
- Data are collected for a planned purpose
Importance of Statistics
The important functions of statistics are:
- Statistics helps in gathering information about the appropriate quantitative data
- It depicts the complex data in graphical form, tabular form and in diagrammatic representation to understand it easily
- It provides the exact description and a better understanding
- It helps in designing the effective and proper planning of the statistical inquiry in any field
- It gives valid inferences with the reliability measures about the population parameters from the sample data
- It helps to understand the variability pattern through the quantitative observations

Frequently Asked Questions on Statistics Definition
What is Statistics?
Statistics is the branch of mathematics for collecting, analysing and interpreting data. Statistics can be used to predict the future, determine the probability that a specific event will happen, or help answer questions about a survey. Statistics is used in many different fields such as business, medicine, biology, psychology and social sciences.
What are the types of statistics?
There are two types of statistics. One type is called descriptive statistics, which focuses on summarising data. Another type is called inferential statistics, which focuses on making conclusions about populations based on samples.
Why are statistics vital?
Statistics is an important field because it helps us understand the general trends and patterns in a given data set. Statistics can be used for analysing data and drawing conclusions from it. It can also be used for making predictions about future events and behaviours. Statistics also help us understand how things are changing over time.
What are the uses of statistics in real life?
Statistics is an integral part of our lives. It is used in the workplace and everyday life. In the workplace, statistics are often used to analyse what works best for a company’s marketing strategy or how to distribute work among employees. In daily life, statistics can be used to analyse what food you should buy at the grocery store or how much money you spend on purchasing each week. Statistics are everywhere, and they help us make sense of the world around us.
What are the most important concepts covered in statistics?
The most important concepts covered in Statistics include mean, median, mode, range, and standard deviation.
