SKILL BENCHMARK
Data Analysis with Python Literacy (Beginner Level)
- 18m
- 18 questions
The Data Analysis with Python Literacy benchmark will measure your ability to recall and relate Python concepts, including using the NumPy library and its arrays for manipulating and analyzing data, and a basic idea of Python libraries such as pandas, Matplotlib, seaborn for data analysis. A learner who scores high on this benchmark demonstrates that they have a basic understanding of Python libraries, visualization libraries such as Matplotlib and seaborn, and basic skills for performing data analysis using NumPy and pandas.
