In today's world, data is not just everywhere; it's everything. From the posts we share on social media to the steps tracked by fitness devices, we constantly generate and interact with valuable data. This data-driven reality is not just a trend; it's a fundamental part of our lives. For instance, when we use a navigation app to find the fastest work route, we leverage data science. Understanding it is not just important; it's essential for our future success and personal empowerment.
While education systems worldwide strive to keep up with the demands of modern economies, there remains a considerable gap in providing data science education before students reach university.
