Ashley Bryant GOL 106 V1. I learned that scientific research must be studied using a control group, a baseline, to compare against a study group, a group that has exactly on variable that is different than the circumstances of the control group and is then compared against the control group to accurately determine what the effect of the given variable is.
For some research, it's beneficial to have multiple characteristics that differ the experimental group from the control group. In my area of research, we're currently exploring the effect gene mutations have on the efficiency of protein activity. Because of the nature of epigenetics and how various genetic loci can regulate gene expression, it's essential to test how various combinations of multiple amino acid mutations affect protein translation and activity. And then comparing the different mutation combinations against one another to identify possible links between genetic loci based on observing a significant difference in protein activity. In this case, the control serves as a way to verify that the proteins were naturally translated and could function at a standard degree of efficiency in the particular cellular environment of the study.
Thank you so much, i was struggling with this topic in my biology class, and I found your video and I was able to get my info correct except for the controlled groups
Question. "The controlled variables don't affect result." I thought the result is den dependent variable? If yes, then the controlled variables have an affect on the result?
The controlled variables are not ment to affect the result. They keep the experimental environment and surroundings the exact same to increase accuracy.
Hi I m a new research scholar..I have decided to conduct an experiment with 1 control group n 2 treatment groups..Shall I take a total of 30 samples for all the 3 groups together?
To determine adequate sample size, you can do a test called a power analysis. A statistician can help with this. Otherwise, you are guessing. 30 samples total (10 per group) may be acceptable, but it’s definitely on the low end and may not be a large enough sample size. If you can reasonably do 20 or 30 per group, that’s probably better. But it’s hard to know without more information and a power analysis.
Why can't everyone teach like this! THANK YOU! You make learning accessible, thank you.
Thank you, Professor. Your explanations are clear, and I now understand the concept.
You knocked this topic out of the part so concisely and quickly. Excellent job.
An expert in the field, a great way of teaching such a complex and technical research
After 2 other video explanations, yours was the one that helped me understand the concepts. Thank you!!!
Thanks! :)
You re excellent!!
I ve been struggling to undertand this
You made it so simple I am aazed
Why don't teachers teach in this wonderful way!
Thank you
thanks Dr Whitney, i was confused about experimental research design but though your explanations now am clearly understanding the concept.

The concepts in your video are so clear, thank you!
Thank you! About to start my research for a business-related degree, and this simple explanation has helped clarify a lot 😊
Precise yet very useful !
Exactly what I was looking for...
Thanks a bunch.☺
Thank you so much, I recommend this because this video makes me more understanding than what my teacher says.
Okeh
Superb explanation, with accurate example
This makes so much more sense now!!! Thank you so much!!
You are a great teacher! I could never understand this concept. Now I can!

THIS IS SO HELPFUL for my sixth grade science class
I'm actually studying experimental psychology, but this is the closest available vid on youtube, i hope it translates well
sound quality could be improved, but you're a natural at this, so keep it up
very informative
Thanks! This is an older video and I have better microphones now.
Thank you for your amazing teaching
Thank you Prof. Really nice explanation
Thanks so much help with my daughters homework
An excellent explanation! Thanks!
I wish my professor explained it this way!!!!!
how do you perform a Design of experiment using different levels of different parameters.
I’m sorry, I need more information to understand what you are asking.
wow! I had a sci lab and this was so HELPFUL!
Thanks!
You’re welcome!

@@BiologyProfessor Thanks a lot for the reply..
Magnificent 👏👏👏👏
Loved the explanation thanks
This is exactly what I needed. Thanks!
Glad it helped!
Thank you for your clear explanation
You’re excellent! Thank u so much for making this amazing video!.
Excellent video!
Dr. Whitney can u make videos based in psychological experiments
thank you
thank you very much but i didn't get the video of scientific method of you
Great video! Thanks
Thank you, you video saves my dissertation
im so happy my teacher toght me dis
It’s a very important topic that is often glossed over
thanks so much very helpful
Thanks!
I got it
Great! 😄
Does she have patreon???
I am afraid not. ;)
Thanks
You are welcome 🤗
perfectthank you so much
Thank you Dr. Whiteny I really Like your explanation , l have very advance questions about groups . can i get you email
Thank you!!!
so thanks mam
Nice!
I still don't understand!! HELP ME, MY HOMEWORK IS DUE IN 14 AND A HALF HOURS
Keep up
does anyone told you that u have very beautiful voice, nose and eyelashes
Why does everyone look like bots
Idk man
fr
why she breathing so loud
How to teach ADHD people 😆
Thank you so much. Great lecture, again.
