I DEFINETLY SUBSCRIBED. EVERYTHING WAS CLEARLY EXPLAINED AND NOW I UNDERSTAND AFTER WATCHING FEW VIDEOS BEFORE THIS.TYSM FOR THE HELP 🤗😁

I enjoyed watching the video. A good analogy of isolation the cause-and-effect using research methods through experimental design as evidenced by the wiggling part you were able to isolate the independent variable.

Your explanation with examples is very to easy to fathom compared to others. Plz keep it up.

[@Feetnt]

This was a fantastic explanation

[@josefinasanchez6528]

Perfect explanation … thank you so much .

Hi, could I ask, if a study involves letting participant watch a video of a well dressed person, and a second video of a causally dressed person, and getting them to select which person they find more trustworthy.
If the hypothesis is that people would find the well dressed person more trustworthy,
Would this entire study be considered an experimental study?

from inductive to deductive in a scientific approach

Thank you for this video. It was helpful :).

[@davidpeterzell5371]

Well done!

[@amandavoesten7055]

The example doesn't involve manipulation, doesn't that make it an observation instead of an experiment? Also the groups are not randomised, so I believe that would make it a quasi-experimental design. Please correct me if I'm mistaken:)

thanks for helping

[@Andrea-ws7bb]

well explained !

[@allisonfernandez7941]

Great explanation.

[@octatonicgardenmarcospi4978]

Why the background music for a technical explanation?

[@erinpanda9245]

Great Video. Thank you for creating it. However, as an instructor of Research Methods I must point out that technically this is a "quasi-experiment". There is no way of knowing for sure here that having TBI "causes" an impairment in recognizing facial emotions . We can't rule out the possibility that these people may just have been poor at recognizing emotions (and were poor at this even before they got the brain injury). The only way to know for sure is to test people's ability to recognize facial emotions in others, randomly select a subgroup to get a brain injury (and another to not get a brain injury), test both groups again and see if there is a change in their scores. Clearly unethical.... Technically, the conclusion that should be drawn from the design described in this video is that people with TBI tend to have more difficulty recognizing facial emotions compared to people without TBI. Sorry to nitpick and thank you again for creating.

A video 10 yr before 😢thankyou

[@LexiLingo]

Thanks a lot

[@rebeccamarical2147]

I would suggest that you delete the the background music. I can't even concentrate on what your saying!!!

[@damola4966]

lol

[@geraldpalma1218]

It's probably too loud but it's groovy

[@ashleyharris2520]

I had issues, It is not playing....

[@theladyja52]

Thank you.😁 I could not find any videos on this topic except yours.
You should search UA-cam and try to find videos nobody has or talks
about.For example I can't find any videos on: CHEMICAL STRUCTURES
ON FOOD FLAVORS and there's not many videos on ENERGY TRANSFORMATION 💯

[@Heelsandholster]

Also try this video on the same topic: ua-cam.com/video/chVvZianMyY/v-deo.html

[@hathawayje]

You were going well until you used a 15/20 and then an 18/20 without saying something about sample size. If the viewer is left to think that they studied two groups of 20 and can make the conclusion you state then the whole video may be a waste.
