What is Statistics?

Statistics is the science of learning from data and making decisions under uncertainty. It applies to a wide range of problems, from detecting fraudulent activity to finding new cures for diseases. While statistics can be used to make predictions about the future, it is also often used to understand the past. For example, historians use statistics to study patterns of population change over time.

Despite its name, statistics is not about numbers. In fact, statistical analysis often starts with qualitative data, such as surveys or interviews. This data is then converted into numerical form so that it can be analyzed using statistical methods. The goal of statistical analysis is to draw conclusions from data that are as objective and precise as possible.

There are many different types of statistical analysis, but all share the same basic steps: collect data, summarize the data, and draw conclusions from the data. The Best online Statistics course will teach you how to carry out these steps in order to answer real-world questions. With a strong foundation in statistics, you’ll be able to tackle any problem that comes your way.


Is it hard to learn statistics online?

Statistics is a branch of mathematics that is used to analyze, organize, and present data. Because statistics is such a broad field, it can be difficult to know where to start when learning it online. 

The best way to learn statistics is to find a course that covers the topics you are interested in and that is tailored to your level of understanding. 

There are many different online courses available, so you should be able to find one that meets your needs. 

Once you have found a course, it is important to follow the instructions carefully and to practice regularly. With effort and perseverance, you should be able to learn statistics online.

How long does it take to learn statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. In many ways, it is similar to other mathematical disciplines, such as calculus and linear algebra. 

However, statistics also has its own unique set of concepts and principles. As a result, it can take some time to master the subject. 

In general, students who have a strong background in mathematics can expect to spend about two years studying statistics at the undergraduate level. 

Those who do not have a strong foundation in mathematics may need to spend an additional year or two acquiring the necessary skills. However, the length of time required to learn statistics ultimately depends on the individual student’s abilities and goals.

Is a degree in statistics worth it?

A degree in statistics can open up a lot of doors. Many businesses rely on statisticians to help make sense of data and to make sound decisions based on that data.

Statisticians are also in high demand in the government and in academia. A degree in statistics can lead to a very successful and financially rewarding career. 

However, it is important to note that a degree in statistics is not always necessary to work as a statistician. Many employers are willing to hire candidates with strong math skills and relevant experience, even if they do not have a formal education in statistics. 

As with any decision regarding education, it is important to carefully consider your goals and objectives before deciding whether or not to pursue a degree in statistics.


So, which online Statistics course should you choose? Our pick of the Best Online Statistics Courses is Introduction to Statistics in R (DataCamp). We highly recommend this course if you are looking for a comprehensive and well-rounded introduction to the topic.

Whichever route you decide to take, we hope that this ranking has helped make your decision easier and that you have now gained the skills needed to tackle Statistics confidently. Feathers down!
