Dear lecturer, I'm very happy with your youtube video presentation because I have been getting valuable inputs for my PhD study. Thank you, but would you please share me if you have a youtube video on the students' speaking performance in English language classroom?

I love when someone makes a video explaining a concept so well that I only have to watch once, but still choose to watch twice

Very clearly explained thank you. However, I believe you could have briefly mentionned the central limit theorem to justify why under the null hypothesis we expect a normal distribution of sampled means. Otherwise, this is by far the best/most efficient explanation on the internet. THANK YOU :)

Martin, Could you do a video on survival analysis one day? I would love to see your handling of the topic (and if you could couple it with R that would be even better).

will do :) and by the way, I have an R programming channel (R programming 101)

Hi Greg, Thank you so much for all your efforts in these videos, they're always so clearly explained! Do you have any videos or will you consider doing any on Regression Dilution Bias? I'm currently studying that in my Intermediate Epi module Thanks again!

Thanks for this presentation but I have a question if p values below 0.05 and average weight of sample falls in that proportion, does that mean this sample having sample mean 75 belong to population that doesn't have average weight of 65kg?

@felixlucanus7922 Жыл бұрын
Nice video. May be also worth noting that an average value is not enough to construct a distribution such as the one drawn in the video. So the hypothesis would have to include more information than just the mean value to construct the distribution.

Terrible explanation. You should probably use more precise language. The "sample falls into 2.5%" in what way?
