Data Science Tutorials for beginners: Data Science Guide for beginners

Nowadays you can see it everywhere: articles, TV reports, blogs and even entire companies dealing with data science. But what exactly is data science? Is it just a fad or something more sustainable? And what do you need to know to have a say and get a job in this field? To be successful in any new area, we recommend starting with the basics. More precisely, with the foundations of this new venture. The world of data science is big and vast, but we’ve found some of the most basic concepts that are helpful to anyone looking to build a career in the field. These tutorials give you an overview of everything from getting started with Python programming to statistically evaluating your data with R.It’s not a complete list – if you want to know all the details about each topic, you have to dig deeper into our blog, but they give you enough information to get you started on your own data science journey.


What is Data Science?

Data science refers to the various possibilities of applying scientific methods and processes for the collection, storage, analysis and subsequent use of data. The data used can be anything from climate data to human genomes. The main goal of data science is to answer questions and solve problems based on data. For example, a weather data scientist uses data to create a model that predicts the weather for the next three days. Data science can be applied in various industries and sectors. Data scientists can work with data to solve problems in healthcare, education, business, and many other areas.

Why learn data science?

There are many reasons why you want to start studying data science. You may have previously worked as an engineer or in another technical field and want to make a transition that allows you to use data and technology in new, exciting ways. Data scientists use technology to solve complex problems in a variety of industries, including healthcare, education, business, and more. Maybe you have already worked in marketing, sales or in another area where data plays a role. It is known that data scientists move from one area to another – especially marketing -, to work with data. You may want to start studying data science because you want to advance your career by acquiring new skills and expertise.

Data science tools and languages

One of the first things you need to learn when you want to start data science is the right tools and languages to use. This depends on the company, the industry, and the desired role, but two of the most important tools you should know are Python and R. It is a very flexible language used in many different industries, including finance, web development and data science. R is an open source programming language used for statistical analysis and data visualization. If you work in an area that has a lot to do with numbers and data, you’ve probably heard of R. It is one of the most commonly used languages for data science and works with a variety of different datasets and data types.

Statistical analysis with R

If you’re primarily interested in statistical analysis – a so-called descriptive approach to data science – then R is a great language for you. R is a free software program that you can use from your computer’s desktop. It’s a perfect, free language for beginners, as you can use simple graphs and charts to analyze data, such as the average or value range, as well as create charts and tables. To get started, you need to download R and set up a program. You can then enter your data into the program by either entering it directly or uploading a file with your data. From there, you can use simple functions such as mean and standard deviation to analyze your data.

Machine learning with Python

If you want to take a predictive and predictive approach to data science, you can focus on machine learning. In this approach, you use different algorithms and statistical models to analyze your data and make predictions about what might happen in the future. Machine learning is mainly performed in Python. This language has been designed to be highly applicable, meaning it can be used for many different applications. Machine learning is about training a computer program to make predictions based on your data. You need to give the computer certain instructions on how to make predictions based on new data that it has never seen before. To do this, you need to know the different algorithms and statistical models used in machine learning.


In summary, data science is a scientific approach to the collection, storage, analysis and use of data. It is a flexible area that can be applied in many industries. To start learning data science, you need to learn the right tools and languages such as Python and R, as well as the various statistical models and algorithms of machine learning. Remember, this is just an overview of what data science is. If you’re looking for a career in this field, you’ll need to learn a lot more – and these tutorials will help you!
