The era of big data is here. But this data is worthless unless a meaning is drawn out of it. It is exactly here that data science comes into play. Data science is nothing but a combination of different algorithms, tools, and machine learning principles. The main objective here is to identify hidden patterns out of raw data. With organizations relying heavily on data, the need for data scientists is at an all-time high. A data scientist is concerned with discovering insights from raw data and adding different machine learning algorithms to recognize a specific event in the future. A career in data science is promising and if you aspire to become a successful data scientist, there cannot be a better time than now to start. On that note, here are the top 10 free data science courses to take up in 2022.
