Thank you for watching the video. Feel free to leave any comments below!
You are officially my math tutor! I'm so glad I found you two weeks ago!
Thank you for your comment :)
Note that you are delighting young minds of the world with excellent conceptual explanations. STAY BLESSED!!!!
Thank you so much for your comment, Alem!
After studying for my MBA with over 70K tuition per year. My statistics professor could not explain this very well
you should of just moved to the west coast if you aren't out here alredy and bought a property and grown weed, would have been easily milliionaire a few times over.
nice!
This was very good and clear thanks
indeed @stas anastasiou... Its really clear. But nowadays many researchers did single blinded experiment, just to make sure that they achieve what supposedly the want to.
totally agree... 101 and very clear
This is one of the best explanations I have ever had on placebo treatment. Keep it up
Thank you for your comment! It inspires me to keep making more videos. Feel free to support me on patreon as it would help me a lot
so happy it was posted 4 years ago a friend recommended it. Hopefully her husband and her are happy in Vegas. A spoon full of sugar or 3-4 taken at the right time.
Clear and simple, pretty straightforward. Love the art style too they're cute hehe
Hehe thank you :)
THANK YOU SOOOO MUCH.
Last minute saviour....
Its all coz of u i could complete my presentation.
Keep uploading videos like this.
ONCE AGAIN THANK YOU
This explanation is perfect.
Thank you so much.. I really appreciate you excellent explanation
uggghhh finally the clearest explanation ...far clearer than my instructor... Thanks for this!
amazing explanation, thank you!
Made my day! Thanks.
great video. You explained everything very clearly and fast, thanks.
I’m here because I have to watch this for school
facts me too
facts me to
This was helpful. I'm curious: when they test out vaccines, do they also do these as placebo/double-blind experiments to check for any potential negative effects?
Yes. If a number of people get sick and all or most of them are in the experimental group and not in the placebo group, then we can tell this is most likely adverse effect of the medecine being tested. However, if there are about as much people who got sick in both groups, then we can attribute the adverse effect to other variables.
I have read or wacth several content in order to understand the topic before but could not understand clearly. You made me understand within a minute
Thank you sir.
I'm glad to hear that! Thank you so much
@@Simplelearningpro
Sir I need more contact of yours
I am a clinical research student
Please help me sir.
Could I get your access sir
This might be a stupid question, but if the experimenters don't know who got what, then who does know? How do they know what the results are at the end of the experiment if they don't know who got what?
I dont know but I suppose there must be someone from outside the experiment that help the researchers with that
hhhhh i had the same question ....Its a smart question not stupid bro
Ah usually there's a qualified third party that is authorized to know which group is which and such and only tells the researchers the results after the experiment is over.
You have to understand more.
There will be a guide for the researcher. He known that what pill has given to whom .
I'm Lucky that I found you it's a bit late but on scale for my sem xams thank u
THIS HELPS ALOT THANK YOU!!!!!!!!!!!!
Thank you for your information. This is why I am declining the Covid vaccine at this time. I consider myself part of the control group!
many thanks, you cleared the dust cloud over me re difference and relations of those issues
u are just awesome, the doubts about this topic that my professor was unable to clear are got cleared now
Each and every word is well researched and well versed.
Easily digested.❤
Self-reporting is also an issue. Could having independent, measurable variables (like, how much can a person lift after taking the pill or placebo) can make the test more stringent?
I'm trying to learn about these methodologies to combat superstitious thinking. Thank you for uploading!
I just started Methods this sememster and I didn't understand a thing but you've just made it so clear and simple! Glad I came across you thank you !!
Glad I was able to help :) good luck with the rest of your learning!
THIS IS ACTUALLY A REALLY GOOD VIDEO AND EXPLANATION
lol i slightly understand now . . .im dyslexic . . .study for my masters in Mental health: psychological therapy .....thank you smart man
Believing something will work doesn't actually make it work... the placebo definition was messing with me a little bit.
3:25 if both of them doesnt know which group is which then it is possible to have the get the comparative data and how can one understands whether the Placebo medicines worked or not
Someone will know. perhaps the pills were give a number code that only the person who made the pills knows. Then at the end of the experiment, everyone finds out the number on their pill represents the placebo or real medicine.
thank you so much for the video, it's was very helpfull :)
thank you this is simplified in amazing way
if I pass my exam I'm every video this person made 😍
Very helpful tutorial and very easy to understand. Truely thanks
you are such a great page to teach very clearly! :) please go on statistics ANOVA, t TEST, REGRESSION, CORRELATION...etc..
Even though the pill may present a statically significant result do you still have to demonstrate the reason why the change occurred?
this was very clear and simple to listen! thank you so much
Thank you so much
Absolutely awesome explaination 🎉
Thank you for this simple explanation!!
Glad I could help!
Best just incredible ❤️
this was rlly helpful thank you 💗💗
Thank you for watching :)
Too much helpful...... we want more from you.
Please explain extraneous variables and randomisation 🙏🙏🙏
Amazing lectures
You are the best ❤❤❤
After studying for my MB A they're cute he 'm so glad I found 4 years
Thank you very much!! I'm having a problem with my science book. If only you didn't help me I might throw my science book away!
Question, if there is a double-blind method, how can we then analyse the results? Asking because I have an exam this Monday. Great explanation btw.
I'm assuming that there's probably another person who knows who was given what
Very nice
What the point of a placebo if you are going to get the same result?
The double blind is so funny to me, but i get it thank you so much
just like vaccine trial right?
I love this video with all my damn heart
I'm kind of shocked as to how well you explained this.
Did you go to school for this? Because I did. And your vocabulary and verbal demeanor is academically familiar
Thank you. And yes, I did go to school!
@@Simplelearningpro Just because you are educated in a subject or topic does not mean you can teach it.
But you taught this better than most teachers I know.
@@jasonspades5628 Thank you so much!
Great videos! Our institution requires closed captioning (not just auto-generated) for any videos we share with students so I cannot show them. :(
We are currently doing our best to work on them!
good video, dude
thanks
I’m the double blinded test, neither the patients nor the doctors know which groups the patients are and placebo or treatment they are receiving. Then who knows?
perfect explanation!
Very helpful, Thanks
That’s assuming plants have no awareness?
Thanks man but also ppl get stronger quicker and sum not so much so u have to factor that in too
this was awesome.. u were quite Apt. thanks
This was great, thank you
সেরা ❤️
Thanks!
Hey Man, u r awesome, which software do you use to make this?
What's the difference between a blind experiment and a double blind experiment?
Both experiment and subjects are not aware. I think in the former either the experimenter or the volunteer will have knowledge. Consent. If you have not given it then all are subject to a lawsuit that they will never recover from. In these cases these types of people will kill or commit suicide. It happened in the chantix study in BC. Yet 43 million poured int BC politics because of power, control and money. who has money right now? who has money to burn? I do not know any North Americans that are that rich. You cannot blame the Chinese on this one. You cannot blame biotech. Let's blame GOD since someone played GOD by posting this in 2015. The person that told me about TH-cam she is in a different state. Let's go loca with conspiracy theories.
0:43 That's actually the Nocebo Effect
Yeah but Nocebo and Placebo are both the same effect in principle. The only distinction is essentially whether we appreciate the results or not, but says nothing whatsoever about the underlying psychogenic mechanisms.
the characters look so harmless and cute lol.
Thnkyouu 😘😘😘😘😘
No problem :) Thanks for commenting!
Whis is this such a good way of teaching? 🤣
goat!!!!!
The opposite is called "Nocebo effect"
IF only they would do this to test the safety and efficacy of vaccines...
Sadly, pharmaceutical companies production of vaccines (unlike every other industry) have NO liability and therefore no incentive to do ANY safety studies.
Ahhh so your an anti vax mom...
I may not be able to get through to you but...
The measles will
@@wetbread4243 this is how antivaxxers attack vaccines.. they try to pin side effects as caused by the vaccine because the efficacy of vaccines it's not questioned.
adfasd lol
@@wetbread4243 study correlation and causation it will make sense to you with a bit of study.
adfasd damn. I don’t really know what your talking about but I hope your not an anti-vax. But I’ll try and understand.
I saw an ASAP Science video where they, in a clause, mentioned that a double blind experiment might some times be unethical. Why is that?
Fakit the patient being tested may need the actual treatment but don't get it while expecting to.
@@mehtabalishahpuffgoawayplease They have to be aware that this is possible, otherwise it is unethical. Most research subjects sign extensive forms acknowledging that they're aware they might get the fake treatment. And they agree to this all the time. :-)
It just depends on what intervention you're testing. For example, we will never have double-blinded randomized trials for smoking being causally associated with lung cancer since it is considered unethical to deliberately bring potential death or great suffering to a person simply as collateral in pursuit of more articulate knowledge.
edit grammar
Awww
Actually, there's a different word for having a negative reaction to something simply because you believe you were going to; the nocebo effect.
Correct.
On a tangentially oblique note, to the best of my knowledge, there exists no evidence suggesting any distinctions with respect to the implicit psychogenic mechanisms.
didn't ask
Can anyone give me 10 facts about his I need it for homework
It’s due in 10 minutes
@@ceciliamaiello3437 Well looks like I'm a month late lol. How did it go?
Lol
This is good and all, but why you so sad?
Homeopathy, are you there?
Thank you so much
Very helpful, Thanks
