Questions are central to research. If Questions are central to research. If there is no question, then the answer is there is no question, then the answer is of no useof no use

Finding answers is the end of all Finding answers is the end of all researchresearch

Purpose of ResearchPurpose of Research

To find an answer to generate ideas for To find an answer to generate ideas for an hypothesis an hypothesis

To test an hypothesis in order to apply To test an hypothesis in order to apply them to real lifethem to real life

Validity/Reliability Validity/Reliability

ValidityValidity The strength of our conclusionThe strength of our conclusion Does the study prove/disprove the hypothesis?Does the study prove/disprove the hypothesis? Researcher’s biasResearcher’s bias

Reliability Can the measurement be repeated? Do you get the same results?

Test/Retest

In order to be valid, a test must be reliable; but reliability does not guarantee validity.
