Finally, a video that actually gives a clear definition and comparison. Took me an hour to finally find the right one

I loved how they got Hermione Granger to voice a cat in an educational science video.

[@asmaabulibdeh1525]

It is absolutely great to have such simple explanations to illustrate concepts instead of huge books (or at least before u start to read related books ) , many thanks ...

Great video, thanks.

Very useful for a beginner just starting to do biology experiment. I love the cat and Dr. Johnson's unorthodox haircut :)

I am a fan of assistant cat😂♥️ This is a great idea to explain these things!

It's just this video after which I could understand the concept well. Thanks!

[@pappoe_rare]

Beautiful. Just beautiful. Thanks

[@mariawilde5300]

All 3 videos, so great! It is not uncommon to see even post-docs to not pay great attention to proper controls when doing experiments. Please, make some more videos! Great initiative

Nice lesson. However, I would like to ask this question: Are you not going to consider the caffeine content in the coffee per N oz cup of coffee as another factor? Maybe it didn't affect the blood pressure because of the small or maybe lacking intake of caffeine for the blood pressure to be altered. If so, then you'd be making many (or in average three, that's what we've been told) test groups with varying amounts of coffee and then assign. That will make your research more reliable. Say test group C with the highest amount of coffee yields an increase in the BP and test group A with the lowest doesn't. This way, you can determine the correlation between caffeine intake and blood pressure and how much of it will affect your BP.

The one question this video didn't answer for me: How did this man get a PhD?

[@Lara-ux1rb]

Seems like he always carried his cat around

[@jeongminchoi309]

Hi I wonder the differences among naive control/vehicle control/negative control.

The marker and the board friction noise is bothering I couldn't follow the lesson even though its a very good explanation. Please consider this.
