Statistics

Welcome to our statistics section! Statistics plays a crucial role in helping researchers make informed decisions and draw reliable conclusions from their data.

In this section, we will cover some essential topics in statistics, including hypothesis testing, choosing a statistical test, factors affecting power, common measures of therapeutic efficacy, and diagnostic studies. Hypothesis testing is a fundamental concept in statistics that involves testing a hypothesis by analyzing sample data. Choosing the right statistical test is also crucial in ensuring accurate and reliable results from your data analysis. We will explore the different factors that can affect the power of your statistical test. We will also discuss the common measures of therapeutic efficacy used in clinical trials, such as the relative risk reduction, absolute risk reduction, and number needed to treat. Additionally, we will explore diagnostic studies and the various performance measures used to evaluate diagnostic tests' accuracy, including sensitivity, specificity, positive predictive value, and negative predictive value.
