Thanks! I am watching this the night before my PhD comprehensive exam.

[@biostatisticsbydesign]

I'm sorry I didn't see this in time to wish you luck, but I hope you killed it! My comps were the hardest part of the PhD for me. It's all easy-peasy from here! :P

[@mjm2b]

Thank you! I haven't made a new video in a while, but comments like this one make me realize it is long overdue!

Dear teacher, could you show us a solved example for power of the test?

[@biostatisticsbydesign]

I have an example in my blog here: www.biostatisticsbydesign.com/blog/2019/1/11/power-analysis-an-underutilized-tool
I hope that helps!

Its funny and I loved it. thanks for making it clear for me.

[@tamimahmed2450]

Thanks for the nice video...just to know....What if the population is unknown? Can we determine sample size by power analysis then?

[@biostatisticsbydesign]

I'm not sure I know what you mean. Do you mean if the expected means are unknown or expected difference is unknown?

it is a misfortune that you stoped publishing

I know I fell off the wagon! But I have plans to make more videos still! I have so many ideas! Stay tuned. I promise to get a new video out soon!
