Without a relevant degree, many wonder whether this path is even open to them and how much prior knowledge they really need. In this article, you\u2019ll learn what qualifications matter, what a realistic path looks like\u2014and at what point becoming a data analyst is the smarter first step.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can you become a data scientist as a career changer?<\/h2>\n\n\n\n<p>Yes, it is possible to switch careers to become a data scientist\u2014but it is more challenging than starting out as a data analyst. Data science requires a solid foundation in mathematics, statistics, and programming. Those who build this foundation through structured continuing education have a realistic chance of success. For many career changers, the <a href=\"https:\/\/stackfuel.com\/en\/blog\/lateral-entry-as-a-data-analyst-this-is-how-it-works-2\/\">Data Analyst: The More Accessible First Step<\/a>, which opens the door to a career in data science.<\/p>\n\n\n\n<p>The demand justifies the effort. Data literacy is one of the most sought-after skills in the job market, and the <a href=\"https:\/\/www.bitkom.org\/Bitkom\/Publikationen\/Der-Arbeitsmarkt-fuer-IT-Fachkraefte\" target=\"_blank\" rel=\"noopener\">Skills Shortage in the IT and Data Sectors<\/a> has been high for years. Anyone who has the necessary background and can demonstrate it has good prospects as a data scientist\u2014but the path to that goal requires realistic planning.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Requirements You Really Need<\/h2>\n\n\n\n<p>For a data scientist, honesty is more helpful than sugarcoating things. The role requires a foundation that you\u2019ll need to build if you don\u2019t already have it. Three areas form the core:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mathematics and Statistics.<\/strong> Data science builds on <a href=\"https:\/\/www.ibm.com\/think\/topics\/statistical-machine-learning\" target=\"_blank\" rel=\"noopener\">statistical understanding<\/a> on: Probabilities, distributions, model evaluation. This can be learned, but it goes beyond what a data analyst needs on a day-to-day basis.<\/li>\n\n\n\n<li><strong>Programming.<\/strong> <a href=\"https:\/\/survey.stackoverflow.co\/2025\/technology\" target=\"_blank\" rel=\"noopener\">Python is the primary language<\/a> in data science. You'll write code on your own to prepare data, train models, and evaluate results.<\/li>\n\n\n\n<li><strong>Machine learning.<\/strong> The heart of the role: to understand, <a href=\"https:\/\/www.ibm.com\/think\/topics\/machine-learning\" target=\"_blank\" rel=\"noopener\">how models learn<\/a>, when to use which method, and how to critically evaluate the results.<\/li>\n<\/ul>\n\n\n\n<p>You don't necessarily need a degree in mathematics or computer science. What you do need is a willingness to seriously build these foundational skills\u2014and a structured path that won't leave you to figure it out on your own.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Important:<\/strong> Be skeptical of programs that promise to turn you into a fully-fledged data scientist \u201ein just a few weeks.\u201c Mastering the fundamentals of statistics, programming, and machine learning takes time. A reputable training program will be honest with you about this\u2014and plan your schedule realistically.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Data Analyst or Data Scientist\u2014Where to Start?<\/h2>\n\n\n\n<p>For many people changing careers, the most important realization is this: You don't have to become a data scientist right away. The two roles <a href=\"https:\/\/stackfuel.com\/en\/blog\/data-analyst-und-data-scientist-comparison-2\/\">differ significantly in terms of the initial effort required<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Criterion<\/th><th>Data Analyst<\/th><th>Data Scientist<\/th><\/tr><\/thead><tbody><tr><td>Focus<\/td><td>Analyze, visualize, and report on data<\/td><td>Develop models, make predictions<\/td><\/tr><tr><td>Mathematics\/Statistics<\/td><td>The basics are enough<\/td><td>A Solid Foundation Is Necessary<\/td><\/tr><tr><td>Programming<\/td><td>Not much (mainly SQL, some Python)<\/td><td>Central (Python, standalone)<\/td><\/tr><tr><td>A Gateway for Career Changers<\/td><td>Easily accessible<\/td><td>More challenging, often as a second step<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The pragmatic approach for many: first <a href=\"https:\/\/stackfuel.com\/en\/blog\/how-to-be-a-data-analyst-tasks-requirements-career-start\/\">Gaining a foothold as a data analyst through a career change<\/a>, gain practical experience with data there, and use that as a foundation to grow into a career in data science. This isn\u2019t a detour; it\u2019s often the more stable path\u2014you\u2019ll start earning money sooner in a data role and build more advanced skills on a solid foundation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Path Through Continuing Education<\/h2>\n\n\n\n<p>For most people changing careers, structured continuing education is the <a href=\"https:\/\/stackfuel.com\/en\/blog\/what-it-takes-to-become-a-data-scientist\/\">The Most Reliable Path to Data Science<\/a>, because it builds up the three skill areas in the right order, instead of leaving you to navigate scattered online courses on your own. Keep three things in mind when making your choice:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Practical focus.<\/strong> You should work on real-world datasets and projects, not just theory. A portfolio of real projects is your strongest selling point in a job interview.<\/li>\n\n\n\n<li><strong>AZAV certification.<\/strong> If the provider is AZAV-certified, the training can be funded through the education voucher\u2014in which case the Employment Agency covers the costs.<\/li>\n\n\n\n<li><strong>Realistic structure.<\/strong> A good continuing education program starts with the basics and gradually moves on to more challenging topics\u2014and it\u2019s honest about the scope and effort required.<\/li>\n<\/ul>\n\n\n\t\t<div data-elementor-type=\"container\" data-elementor-id=\"88288\" class=\"elementor elementor-88288\" data-elementor-post-type=\"elementor_library\">\n\t\t\t\t<div class=\"elementor-element elementor-element-218a7ecc e-con-full stf-exclude-from-toc e-flex e-con e-parent\" data-id=\"218a7ecc\" data-element_type=\"container\" data-e-type=\"container\" id=\"beratung\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5dd5fd76 sf-clickfunnel-blog elementor-widget elementor-widget-sf_clickfunnel_renderer\" data-id=\"5dd5fd76\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"sf_clickfunnel_renderer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<form id=\"step-form\" class=\"azav_clickfunnel\" action=\"\">\r\n            <div id=\"form-head\"><\/div>\r\n            <div class=\"headline\"><h2 class=\"elementor-heading-title elementor-size-default\" style=\"text-align: center;\">Are you eligible for funding for your further education?<br \/>\nFind out in 1 minute<span class=\"color-lime\">.<\/span><\/h2>\n<p>Choose the right option for you<\/p>\n<\/div>\r\n            <div class=\"after_submit_headline\" style=\"display: none\"><h3>Thank you for your inquiry!

Age and Changing Careers<\/h2>\n\n\n\n<p>A question that comes up time and again in consultations: \u201eAt 30, 40, or older, isn\u2019t it too late for me to get into data science?\u201c The answer is a resounding no. What matters in data science is expertise and the ability to solve problems with data\u2014not the age listed on your resume.<\/p>\n\n\n\n<p>On the contrary: Career changers often bring something that recent graduates lack\u2014professional experience, expertise from another industry, and an understanding of the real-world problems that data is meant to solve. Someone who has worked for ten years in retail or healthcare and then studies data science often understands the questions behind the data better than someone without that experience. Your background isn\u2019t a disadvantage you need to explain\u2014it\u2019s context that makes you valuable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Here's How to Finance Your Start<\/h2>\n\n\n\n<p>In many cases, you don't have to pay for data science training yourself.

Data science requires a solid foundation in mathematics, statistics, and programming. Those who build this foundation through structured continuing education have a realistic chance of success. For many, becoming a data analyst is the more accessible first step.<\/p>\n\n\n\n<p><strong>What are the requirements for a career change into data science?<\/strong><\/p>\n\n\n\n<p>Essentially, there are three areas: mathematics and statistics, programming (primarily Python), and machine learning. A degree in a related field is not strictly necessary, but a serious commitment to building these foundational skills is.<\/p>\n\n\n\n<p><strong>Is it too late to get into data science at 30 or 40?<\/strong><\/p>\n\n\n\n<p>No. In data science, what counts are expertise and problem-solving skills, not age. Professional experience in another industry is often an advantage because it helps you understand the real questions behind the data.<\/p>\n\n\n\n<p><strong>Data Analyst or Data Scientist\u2014which is easier to get into?<\/strong><\/p>\n\n\n\n<p>The role of data analyst is much more accessible: less math, less programming, and a faster way to get started. For many people changing careers, it\u2019s a logical first step that opens the door to a career in data science.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Let's take a look at your path together<\/h2>\n\n\n\n<p>Whether the direct <a href=\"https:\/\/stackfuel.com\/en\/weiterbildung\/data-scientist-training\/\">Getting Started with Data Science<\/a> Whether this is a realistic option for you or whether the Data Analyst role would be a better starting point depends on your background and your goals. <a href=\"https:\/\/stackfuel.com\/en\/consultation\/\">During the free consultation, we'll take a look at your situation together<\/a> and find the path that's right for you\u2014honestly and without pressure.<\/p>\n\n\n\n<p><a href=\"https:\/\/stackfuel.com\/en\/\">StackFuel<\/a> has been AZAV-certified since 2020. 8,000 graduates have completed continuing education courses in data and AI with us, with a completion rate of 93 percent.<\/p>","protected":false},"excerpt":{"rendered":"<p>Data Scientist gilt als einer der spannendsten Datenberufe \u2013 und als einer der anspruchsvollsten f\u00fcr den Quereinstieg.
