How i can download the excle file?
what if we have skewed distribution
Great explanation thank you
If i want to find the p value next, how would i go about it?
the only think I didn't get was how to do that copy trick! but Everything else was great
schools 💀💀
Thanks sir
Does the app work good on mobile phones?
could you pls share the datasets.
This is the best instruction for calculating z-scores, thank you so much! My struggle is over :D
pls show me how to draw the curve with help of the showed data on right side
how do you lock the cells?
was also wondering
Me too
At minutes 4:25 I think there's a typo with you square root on the denominator, since you already power (1/2) - Formula
Excelente video!!! Muchas gracias!!!
There is no sound at 6:45 - 11:00 min
Great breakdown!
In the multivariate gaussian mixture how insert the proportion in R?
There's no volume after the music ends at the beginning.
Ohhh, Can't explain the situation but Thank you for showing what value to take mean, sd and cumulative. thank you very much.
Good info but, please, a little slower
you can just reduce the playback speed by clicking the cog for settings
Hey I get a zero for covariance but there is correlation for the data set in excel.. please help.
Hi, just a question, are those courses for collage or senior high students? because I'm an incoming senior high student, so I don't have any courses to enroll in, so my canvas account is empty because I'm a new student
Binned variables = "recoding", right?
🤤 ρɾσɱσʂɱ
Maybe I am reading the last slide wrong, but is the expected value is the most likely value? A dice has an expected value of 3.5 but this value is not on the dice...
legend thanks!
Do you have a continuation for this lesson? A module 2, perhaps? This was really informative and helpful.
very educative video,
This helped so much! Thank you!
Glad it helped!
Really detailed and well explained. Thank you.
Glad it was helpful!

This is an example I am looking for
Perfect tutorial for my test!!
Great video. Helped me out lot to perform sampling for my study
Great to hear!
Thank you so much for this detailed explanation. I was baffled about these blocking variables not until I listened to your description. Very helpful!
Please share the excel file. Thanks. Carol a student
Well done, how about if we have more than strati? i.e. gender and also marital status and has children or not. How can we do the same logic? Thanks.

Is there programming in Business Analytics modules?
Hi, Do we have to make a new Canvas account for each School? Appreciated! Thank you, very much.
Great video, a pity you didn't include an example of how you calculate for CDF.
That isn't a rounding error. The expression should be 1/n, which will give you 13.9264 (taking your 13.97781*271/272), which is the same as what excel gives you
Adding to this, that is the difference between calculating based on a *Population* and a *Sample.* For a sample, N-1 is used. Excel, unless specified, calculates based on a population.
if my total sample size is 10 participants and I want to enroll them in two groups (intervention and control groups) for a crossover RCT study. what is the best type of randomization should I adopt and how would I do it? Thanks
sir how can can i get the excel file
sir can i have that excel file
Hi, what is the difference between z-score and z-score (excel)? And what is the purpose for doing that specifically?
Can you provide the reference for this talk? I wanna quote it by reference so, Would you help?
Can i get your email I really need a help on something? Would be appreciated
Thanks, I was wondering why Covariance was giving different values to my manual calculations. Thanks for the detail explaining it was just rounding errors.
Glad it was helpful!
