[@andream656]

Thank you for this. Please excuse my ignorance, but do you have the full reference for the Shipman questions used ?

[@aminatasheriff3401]

Thanks for the lectures ,its really educative

[@ThePatriciaGem]

excuse me Graham R Gibbs
may i ask? what is the pattern of arrow target for the measurement/research that have validity but not reliability? is this kind of research really exist?
sorry for my bad english
thank you

[@GrahamRGibbs]

Validity means we are measuring or researching what we think we are measuring or researching. In particular the measure should be free of systematic error. Reliability means getting results in a consistent way. So a measure that is valid, that is, it measures what we think it does and not some other variables, can be reliable or unreliable. For example, it may be unreliable because its value varies a lot from occasion to occasion or with different researchers.

[@daviddowdle3698]

See: www.documentingexcellence.com/stat_tool/reliabilityvalidity.htm

[@jhonanthonybatayola5116]

How can one test the validity and reliability of a theory? sir?:) thanks.

[@GrahamRGibbs]

Jhon, these terms refer to empirical investigations, studies and not to theories. Our study is valid if it measures what we think it measures and it is reliable if our study is repeated by other people and on different occasions and gets the same results. Theories are used to try to explain why we get the results we do or possibly to generate ideas that we can test empirically. Theories are judged by how well they explain the facts or how much they predict.

[@jhonanthonybatayola5116]

ohhh got it sir thankyouu very much:)

[@maramezina1094]

Theories can help us in establishing content validity
