To become a senior data analyst, you typically need a bachelor's degree in a related field such as statistics or computer science. Essential skills include expertise in data analysis tools like Python and R, data visualization, statistical analysis, and proficiency in SQL. Additionally, strong problem-solving, communication, and project management skills are crucial, as well as several years of practical experience in data analysis roles.
If you are planning to get into data science, then I would suggest you enroll in this Advanced Certification in Data Science and AI by Intellipaat. This program helps you develop the required skills. Along with that have a look at this video about Priyavrat Kagzi and how he bagged a data science job with a good salary hike just after completing course from Intellipaat.
