Key Concepts and Terminology

Understanding biostatistics involves familiarity with several key concepts and terminology. Some of the fundamental terms include:

• Hypothesis Testing: A method used to determine whether there is enough statistical evidence to support a specific hypothesis. It involves comparing observed data to what would be expected under a null hypothesis (no effect or no difference) and determining the likelihood of observing such data if the null hypothesis were true.

• P-values: A p-value is a measure of the probability that the observed results occurred by chance. A low p-value (typically less than 0.05) indicates that the observed effect is statistically significant and unlikely to have occurred by chance alone.

• Confidence Intervals: A confidence interval provides a range of values within which the true effect or parameter is expected to lie, with a certain level of confidence (usually 95%). It offers a measure of the precision of an estimate and helps to convey the uncertainty associated with sample data.

• Sample Size: The number of participants or observations included in a study. Determining an appropriate sample size is crucial for ensuring that the study has enough power to detect a meaningful effect and to generalize the findings to a broader population.

• Randomization: A process used to assign participants to different groups in a study randomly. Randomization helps to eliminate bias and ensures that the groups are comparable at the start of the trial.

By mastering these concepts, researchers can design robust studies, analyze data appropriately, and draw valid conclusions from their research findings.
