You are the great in teaching econometric! I MBA-Leadership final semester student, am listening your tutorials when confront the problem. I am from Afghanistan. Wish you healthy life to produce more instructional tutorials!
Thank you for the video. Can you provide any insight as to where proportion comes from other than just it’s given or use 0.50 to get the highest proportion.
I'm a little late, but why does the sample size needed lower when the proportion lowers? Assuming something is highly unlikely (let's say 0.06% , so 0.0006) the minimum sample size we would determine for 99.7% confidence level and 1% margin of error is ~53. Which makes it highly unlikely that we'll encounter that unlikely event at all. Is that caused by our margin of error? As we'd be fine to measure a 0% probability, since it's
how do you get the proportion? i know how to find the margin of error if had enough necessary data but anyway it will be said on the exam, but my question is how do we get the proportion?
Margin of error is a value you (or the task you are supposed to solve) choose yourself, assuming 95% confidence level a margin of error of 2% would mean that 95% of the time the proportion you measured will be at most 2% more or less than the actual proportion. The proportion can be either assumed (look for "educated guess" here: newonlinecourses.science.psu.edu/stat506/node/11/ ) or you just assume the worst case (basically the extrema of the graph shown at the end) - which would be 50%

Hi, but how did you get .025 Margin of Error?
wow i have been trying to solve the sample size and here i learn in just one minute
awesome!!! fan of yours!!

You are fantastic- clear and easy to understand. Thank you.
Thankyou. It was simple and quick.
You are competent sir keep it up 💪💪💪
how do we determine the margin of error?
how do we know p= 0.25???
u r really good. u need to make this faster and give examples.
How do you calculate the sample size if you are only given the population proportion, percentage and width of the confidence interval?
it is helpful...much respect to you

what if you don't know the margin of error?
cool but how the FUCK do you get margin of error and proportion??!!!!!
