Document Summary
Biostatistics is the application of statistical methods to the solutions of biological problems. Make strongest conclusions from limited amounts of data. Over come 2 problems: distinguish signal from noise important differences are hidden by biological variability and experimental imprecision making it difficult to distinguish real differences from random variation. Quality control sample randomly selected from overall population. Political polls random sample of voters is polled and results used to make conclusions from entire population of voters. Laboratory or field of experiments data from experiment performed is the sample if you repeat the experiment you would have a diff sample data from all experiments you have performed is the statistical population. Basically you use the sample data to make inferences about the ideal situation (statistical population) Population is assumed to be infinite or very large compared to sample all statistical methods in this course are based on this assumption.
