hypotheses testing
Hypothesis testing is a method used to decide whether a specific idea or assumption about a group or situation is likely true based on data. You start with an initial idea (the hypothesis), then collect evidence to see if it supports or contradicts that idea. If the data strongly suggests the idea is unlikely, you may reject it. If not, you keep it. It's a structured way to make informed decisions from evidence, often used in research, quality control, and experiments to validate or challenge assumptions reliably.
