two-sample test

A two-sample test is a statistical method used to compare two groups or sets of data to determine if they are different from each other in a meaningful way. For example, it can help decide whether two different diets lead to different weight loss results. The test calculates a measure of difference and assesses whether this difference is large enough to be considered statistically significant, meaning it’s unlikely due to random chance. It’s a useful tool for making informed decisions by objectively evaluating whether two groups truly differ in some aspect.
