Inference for Two Proportions: Introduction

[@jbstatistics]

Thanks for saying you appreciate my videos Isaac! I'm going to be giving a lot more thought in the near future to what to do with all of my videos. Right now I'm still focused on producing content. I've got a few more videos in the can, a few more lined up, and some deadlines to meet. But I'd likely be open to something like your suggestion. I would like to maximize the value of these videos (from a global education standpoint). Cheers.

Thanks! I very much appreciate the kind words. I would just like to add that although in these videos I try hard to be concise and get to the point without undue rambling (unlike in this response), I also try very hard to be true to statistics. I do have some how-to videos, but I am always trying to help students understand the logic and goals of the different methods and procedures.

Mr professor Thanks for your comprehensive discussion I've got a question here 00:51 I assumed in such scenarios we use a chi-square test for independence. However this new method of inference on proportion have baffled me a little bit. I do not know exactly why chi-square test is not done here for comparison of probability distributions I would appreciate if you can elaborate on this a little bit. Thanks a lot for the great job👏👏👏🌷🌷🌷

no offense to khan, i think he's awesome. but jbstats vids are a lot more to the point. khan is great for understanding the intuition behind things, but i like jb a lot more for immediate academic application i.e. hw or exams

I still don’t know what’s happening.. it’s ok I’ll just let it be

I need an explanation to this question ; explain a test about the difference of 2 population proprtions in detail( hypothesis, assumption,test statistic,critical value etc) Came accross this question in a quiz, but i cant seem to solve it easily jbstatistics

Shoot for 100%, but it's awfully hard to say what grade you deserve in W13 at this point in time.

Hello. Thank you a lot for your video. When you calculate the Sample deviation error SE, why don't you divide by (n1-1) and (n2-1), instead of dividing by n1 and n2 ?

When will make for statistical inference...??

[@AshishBudhiraja]

could you please give some insights on what tools do you use to make these videos??

[@jbstatistics]

The base is a Latex/Beamer presentation. I annotate the pdf with Skim, and record/edit using Screenflow. Cheers.

I really appreciate your videos. Educational internet media is the future! Have you ever thought about collaborating with Khan Academy? They may be able to use your help.
