The Three Key Skills for Data Analysts

1. Statistical Knowledge

Data analysts must have a solid grasp of statistical principles. This requires familiarity with probability theory, inferential statistics (such as hypothesis testing and regression analysis), and descriptive statistics (such as mode, median, and mean). If you want to get to the bottom of data and make smart judgements, statistical analysis is your tool.

2. Programming Skills

Data analysts must be proficient in SQL, Python, or R, among others. Data analysis, visualization, and manipulation are prominent uses for these languages. Python and R have gained immense popularity due to their vast libraries and tools that are designed to assist with data analysis.

3. Data Cleaning and Wrangling

Before data can be analyzed, it must first be cleaned and organized. Managing outliers, missing values, data type transformations, and dataset mergers are all part of this process. Data cleaning and manipulation skills are highly valued when working with tools like Pandas or Dplyr.
