A Basic Introduction to Applied Statistics For 2021

Ajay Ohri


Our way of thought and approach to obtaining the most detail from numbers with uncertainties are based on Applied Statistics. It stresses the comprehension of the issue or market. Applied Statistics approaches a method that combines domain and statistics in the vein of Deming or Six Sigma. This article will learn Applied Statistics, fundamentals of applied statistics, statistics and data analysis, and types of applied statistics.

In this article let us look at:

  1. What is Applied Statistics?
  2. What is the difference between Applied Statistics and data science?
  3. Statistics and Data Analysis
  4. What do Statisticians do?

1. What is Applied Statistics?

The term applied statistics is used to describe the work of trained statisticians who are in charge of the processing and dissemination of statistics, as well as the statistical analysis processes carried out by statisticians, professional users of statistics, and the general public.

Companies are looking for statisticians, data analysts, data scientists, and other experts with Applied Statistics experience who can visualize and analyze data, make sense of it all, and use it to solve real-world challenges, thanks to today’s expanded access to big data. Companies have a lot of data, and correctly evaluating it will help them become more efficient and profitable. Data can be used by government departments, non-profits, and other organizations to help mitigate illness, gather critical population data, direct election efforts, and research potentially life-saving prescription drugs.

2. What is the difference between Applied Statistics and data science?

Applied Statistics is ideal for professionals who want to develop a deeper understanding of the scientific foundations of statistical theory and receive specialized training in model construction. Since this emerging field has its origins in mathematical theory, those interested in this career direction will undoubtedly study data science principles. Applied Statistics usually includes learning programming languages like SAS, R, and Python. Those who earn an Applied Statistics degree can be confident that employers are familiar with the skillset obtained through this degree program, especially considering Applied Statistics was recently rated the second-best master’s degree for jobs by Forbes.

Data Science is an excellent course for people who want to learn how to mine data to make forecasts and data-driven decisions, most certainly in a business setting.

Data science aims to derive information from vast volumes of data to eliminate mistakes and enhance market acumen. It helps to have not only the ability to detect trends in data but also the ability to obtain, reorganise, and manipulate data.

Though Data Science is cutting-edge and forward-thinking, employers can be sceptical of its legitimacy due to its youth.

3. Statistics and Data Analysis

Data analysts, including statisticians, detect and distribute data-driven perspectives that help market leaders make smarter decisions. Nearly all sectors, at least to some extent, need professional data analysts. Sales, communications, hospitality, and various sciences are among the industries with the highest demand.

Data analysts also collaborate with other members of a team to complete tasks or solve problems. Since the majority of work is performed on a computer, this area allows for remote work. While statistics and data analytics can seem to be the same thing, at first sight, there are some significant discrepancies between the two fields. Statisticians, on the other hand, must be committed to their work’s computational existence and have strong confidence in their abilities to solve complicated mathematical equations.

4. What do Statisticians do?

A statistician is a person who collects data that is important and necessary for their study. In the fields of science and academia, statisticians have played along and significant role. The market for statisticians in the corporate sector has increased due to the emergence of data generation. Statistical models and techniques are applied to real-world problems by experts in the field. They collect, analyse, and evaluate data to assist businesses in making decisions.

The activities that statisticians are supposed to complete regularly can vary depending on the sector and company in which they serve.

In general, statisticians in the corporate sector work to analyse statistics to inform operational and market plans. In the public sector, however, studies are often based on advancing the public interest, such as gathering and reviewing environmental, demographic, or health data.

If a statistician works for the government or the private sector, their regular responsibilities are likely to include:

  • Data collection, analysis, and interpretation
  • Detecting patterns and connections in data
  • Processes for data collection design
  • Stakeholder communication of results
  • Providing strategic advice to organisations and businesses
  • Assisting in the making of decisions


You use statistical methods and technological instruments such as spreadsheets to solve real-world challenges using data in Applied Statistics. It incorporates the science of gathering, arranging, and analyzing numerical data, focusing on mathematical inference and data interpretation.

Learn about research architecture, descriptive statistics, probability theory, and statistical inference, as well as whether to use one- or two-sample t-tests, one- or two-proportion tests, correlational approaches, regression analysis, and analysis of variance. Although applied statistics is rooted in statistics, computer science is more of an extension of the discipline, focusing on machine learning, software engineering, and database administration, whereas applied statistics is rooted in statistics. However, statisticians and data scientists often serve on the same staff, and job duties and tasks can differ depending on the position being filled.
