Frequently asked questions
How do I verify my Data Analysis skills on Lemma?
In a peer session, you work through a dataset: cleaning, exploring, visualizing, and drawing conclusions. Your partner evaluates your methodology, tool proficiency, and ability to communicate findings clearly.
What does a Data Analysis SCI score measure?
Your Data Analysis SCI measures competence in data cleaning, exploratory analysis, statistical reasoning, visualization, and communicating insights to non-technical stakeholders.
What tools should I be comfortable with for a Data Analysis session?
Python (pandas, matplotlib) or R are most common. SQL proficiency is expected. Sessions focus on your analytical reasoning more than specific tool mastery -- use whatever you are strongest with.
How does Data Analysis verification compare to a DataCamp certificate?
DataCamp certificates prove course completion. Lemma verification proves you can analyze real data, handle messy inputs, and communicate findings with a peer evaluating your entire process.
