# Present Insights from Course Supply and Participation Data You are given one table showing the current number of courses by category and another showing course counts and participation over time. Explain how you would analyze the data and present your findings in a concise slide presentation. No numerical values are provided, so describe the comparisons, charts, and conclusions that the data could support without inventing results. ### What a Strong Answer Covers - Verification of table grain, time coverage, and whether participation is users, enrollments, or another unit. - A distinction between catalog supply, participant demand, and normalized utilization. - Category comparisons and time trends that account for stock versus flow and changing catalog exposure. - A presentation that separates observed patterns from causal claims or unsupported recommendations. ```hint Compare like periods A current course inventory is a stock; participants measured during a month are a flow over that month. ``` ### Follow-up Questions - Why could participants per course fall while total participation rises? - What further data would help evaluate whether adding courses caused higher participation?
