Technical Skills

Any duty associated with data analysis requires well-developed skills or technical capabilities. So, building a career in Data Analysis means building various sets of technical skills, including programming skills. Below, we have compiled and briefly explained major Data Analyst technical skills for you to explore.

• Python Programming Language
  Python has become the first choice for data analysts due to its simplicity, versatility, and extensive library support for data manipulation and analysis. The language is easy to learn and has a strong community, making it an excellent choice for beginners and experienced analysts alike. There are various uses of Python for Data Analysts, so getting your basics in Python strong will help you in the long run.
• R Programming
  R is a popular statistical computing and graphics language used in academia and research. It offers a rich ecosystem of packages and tools specifically designed for data analysis, making it an essential skill for data analysts working with complex statistical models.
• SQL
  SQL is a domain-specific language used for managing and querying relational databases. As data analysts often need to retrieve and manipulate data stored in databases, proficiency in SQL is crucial for efficiently extracting and filtering relevant information.
• Data Manipulation and Analysis
  These are critical components of the data analyst’s skill set, as they involve transforming raw data into meaningful insights that can drive informed decision-making. Data analysts must be proficient in data manipulation techniques, such as cleaning, filtering, aggregating, and transforming data, to ensure its accuracy and reliability before performing any analysis.
