What is statistics?
Statistics is the mathematical science and practice of collecting, analyzing, and presenting data. Data scientists are the primary users of statistics, although scientists, government agencies, and other researchers may use statistics to collect and interpret certain datasets. Understanding statistical data allows students to identify trends, deficiencies, and common occurrences between datasets and assign numerical values to this information. For example, a data scientist might determine that 50% of college-educated people earn more than $40,000 a year, according to statistics. This foundation is essential for data professionals, including biostatisticians, as discussed in biostatistics in healthcare.
What do you learn from statistics?
Studying statistics allows you to master several mathematical techniques and can help improve your analytical and reasoning skills.
Here are some examples of what you can learn from statistics:
- How to create charts, graphs, or other organizational schemes to represent data
- How to collect accurate data for plotting or measurements
- How to analyze data for specific information
- How to spot data trends, gaps, or commonalities between datasets
- How to determine specific information about datasets, such as means
- How statistics influence public opinion and action
- Why statistics matter.
These concepts also lay the groundwork for business analytics valuable to IT professionals. For more on this, see business analytics for IT professionals.
Why study statistics?
There are many benefits to studying the field of statistics, even if you are self-taught. These benefits may include the following:
- Sharpen your problem-solving skills: analyzing statistical information can help hone your problem-solving skills and make you a better problem solver, professionally or at home.
- Improve your analytical skills: studying statistics can help you improve your analytical skills for better decision-making.
- Improve your financial skills. Statistics often include financial datasets. Understanding these datasets can improve your overall financial skills and help you improve your financial discipline.
- Help experts make smarter decisions: data scientists can help professionals, such as physicians, make better care decisions using statistics.
- Improve your math skills: math skills can be highly desirable for some employers, so learning statistics can improve your skills and allow you to look for better job opportunities.
- Help make more accurate forecasts: By using statistical data, you can help make more accurate forecasts on various subjects or trends, such as financial or healthcare trends.
As the field continues to evolve, the practical value of statistics grows across careers in technology, healthcare, and business. For a broader view of how these skills translate into a career, check out the The Promising Future of Data Analytics.
How to learn statistics yourself
Here’s how you can learn statistics yourself in four easy steps:
Learn the basic concepts
You can start learning statistics by studying the basic concepts of the discipline. This includes:
- Descriptive statistics: A single descriptive statistic is a statistic that summarizes similar features or trends in a set of similar information. The plural form of this word describes the process of analyzing these statistics and using them for some purpose.
- Probability distribution in statistics measures the likelihood of different outcomes in a given experiment. This method helps data scientists determine the most likely outcome using mathematical variables and constants.
- Hypothesis testing: in statistics, researchers often make hypotheses, which are educated guesses about datasets. Testing these hypotheses helps determine if they are correct and what factors influence the outcome.
- Regression analysis in statistics is the evaluation of the relationship between different variables.
As you build these foundations, you may want to explore additional career insights in data analytics. For example, How To Become A Data Analyst offers guidance on turning statistical skills into a job path.
Explore Bayesian and frequentist approaches
Keep in mind that Bayesian and frequentist approaches are two different approaches to statistical data. You can learn one or both, but it’s helpful to at least learn the basics of each for a complete understanding of how statistics work. Essentially, frequentists only study the probabilities that can happen to the data they have collected prior to analysis. Bayesians follow the same process, but also account for statistical uncertainties before collecting data. The method you choose to master can change the way you approach statistics, so determine which one can better suit your needs before you take on any of them. If you’re considering formal education in this area, explore why pursuing an online MSBA degree could be a strong option.
New tools and approaches are making statistics more accessible, including AI-driven methods for data problem solving. For practical tools, you might also look at AI tools for math problem solving.
Explore machine learning
It is not a secret that machine learning can be an important component in the field of statistics, as machines and artificial intelligence help us create and analyze statistical models. Learning how machine learning works in statistics will help you get a better understanding of modern statistical applications and teach you some basic coding skills. Studying AI and machine learning can also help you prepare for advanced computer algorithms or other software if you pursue a career related to data science.
Now you can start learning statistics to handle modern data challenges. Follow our tips, and you will succeed.
