3.11 Validity and Reliability Of Research 

I am writing a dissertation and giving a thorough explanation about the validity and reliability of my instruments is a challenge at the moment. Thanks for posting this video, it is helpful.

I love this mans accent! Helps me understand better somehow.

after a long search finally a simple explanation found for beginners like me! a gold video, thank you..

I can’t be thankful enough for you🙏🏻🙏🏻 u saved me, I am a master student in korean uni, I don’t understand most of the classes but u helped me with this topic🌸🌸

I'm taking Psychology 2430 and your video helped my to Understand my chapters and better prepare me for developing my research assignments

Outstanding and clear explanation.....you have helped me tremendously today!!!!!! Keep up the great work!!!

Thanks! When you said Representativeness was hard to say, I tried saying it, thinking that as an English native I'd be able to do it (even though I see that it is still hard for those who arent english natives). So I thought I'd prove you wrong to myself for fun, but then I couldnt say it right, either!

Thank you for this video, great explanation of the terms with useful examples and helped me to prepare for my research test.

thank you so much, the video has been very helpful

Exactly the kind of explanation I was looking for. Such a succinct one. Thanks

Thank you very much for your explanation. I am an MSc Psychology student and I need to understand the topic well in order to succeed with my specific research module. (Experimental Research Methods) Once again, Thank you for your help and support.

wow!! so clear is your explanations thanks a lot !! ^-^

Tones of books and none of them have explained it as you!

this saved my life second to Jesus!!!!!!!! Thanks ...

Thank you so much, I really found this video very useful to grasp these concepts!

Good presentation. Thank you

7 years ago and it's amazing ... thankyou sir Very helpful

Big thanks... Happy because I found yr channel

Thank you very much for this! Clear and helpful guidance

wonderful, great explanation finally...thank you.

Thanks this has helped me understand a question I was asked

PLEASE, Is exploratory factor analysis the same as convergent and discriminant validity? I am a little bit confused. Thanks in advance for your reply. Should we do both convergent and discriminant validity, construct validity using EFA in one study?

thanks a lot, this video helps me escape from a pool of vagueness

great insights....

Very clear explanation... Thank you so much

Woooww you explained this perfectly well thank you🤗

thankyou for such a simple explanatory lecture. like your way of slow explanation so that everyone can get what is reliability. :-)

Many thanks for the remarkable explanations. One thing I wonder (at minute 5:58), wasn't it supposed to be "explain from most general themes and justify to a most concrete one. for example, from exploratory study to inductive, then more specific perhaps to quantitative". I wonder, normally inductive research is paired with qualitative techniques, rather than quantitative, isn't it? thanks.

Thanks for the video! Could you please provide a citation for participant error?

Thank you for your explanations. It helped tremendously.

Thank you so much for your video!! Can such terms be used to discuss and critique a healthcare test (for example a scan) or only be used for research?

Doesn't inductive research approach imply qualitative method, and not quantitative method as stated in the video?. 5:54 . Maybe you just get confused but that confused me as well.. By the way great video! Most of BBA student in Brussel will pass RM thanks to your videos!

Amazing video! Concepts never seemed more clear

around 6:00 you said, exploratory research leads to inductive methods, which then leads to quantitative? shouldn't it be qualitative? inductive reasoning is from specific to general... right?

perfect explanation thank u

One question sir...if a physician is measuring a phosphorus level and and dermatologist doing skin biopsy and the result is significant...does this study have limitation with internal validity???

Thank you for the wonderful explanation.
