Practice with synthetic data
CSV files are analyzed in your browser and are not uploaded. Use synthetic or fully de-identified teaching data. Do not enter patient identifiers.
Maximum 2 MB and 10,000 rows. The first row must contain unique column names. Numeric columns use a decimal point; blank cells are missing.
Unweighted descriptive summaries only. Sample SD uses n−1. This lab does not fit models, test hypotheses or handle complex-survey inference.
