Biostatistics Without Fear
Read results sections with confidence: p-values, confidence intervals and risk explained without fear.
What is Biostatistics Without Fear?
Statistics often stand between healthcare professionals and the research that should inform their practice. This course focuses on understanding and interpreting statistics rather than calculating them by hand: types of data, averages and spread, p-values and confidence intervals, relative and absolute risk, number needed to treat, sensitivity and specificity, and common ways statistics mislead. Every concept is illustrated with realistic results from healthcare studies.
