1.The purpose of various statistical testsThe purpose of various statistical tests is to validate hypotheses, quantify uncertainty, and draw meaningful conclusions from data.
These tests help determine whether observed patterns in data reflect true relationships or are due to chance.
They provide mathematical rigor, enable reliable inferences, guide predictive model development, facilitate comparisons over time, support objective decision-making, and enhance reproducibility in research.
There are numerous statistical testing methods, each suited for different types of data and research questions. Below is a table summarizing some common statistical tests along with their definitions:
