Decision logic
How this tool reaches its result
Test choice follows the outcome type, number of groups, independence, distribution and research question.
Worked context
How to interpret the output
A continuous outcome compared across two independent groups commonly points to an independent-samples t test when assumptions are reasonable.
Important limitation
What the result cannot decide for you
A recommendation is a starting point. Confirm sampling, assumptions and the analysis plan with your instructor or statistician.
