INCREDIBLE VIDEO!!! Guys, listen up -- for my Step 1, Dr. Neil's videos were an absolute MUST. They single handedly got me through Biostats. You all NEED to watch the full set of his videos explaining the high yield principles that they're (likely) going to test you on. It's all HIGHHHHHHH YIELDDDDDDDDD

best anime crossover ever

24:00 although it yielded the right answer i think theres a mishap in solving this. Because-- we first calculate whats the chance of a healthy new donor. Thats 2q = 1/150. (Because q=1/300) Now that healthy donor passing the recessive allele is another 1/2 chance from mom is 1/2 so 1/2 x 1/150 x 1/2 = 1/600. thats the proper way of solving.

Hello thnku for ur comment, but can u explain y u did 2q? thats the part i coudnt understand.

@banya159

@@mrinalinibuddha9033 q is diseased allele frequency. Now the sperm donor must be heterozygous normal if he is healthy phenotypically but still carry a copy of diseased allele. From the equation the heterozygous carrier frequency is 2pq. In these types of autosomal recessive diseases, they say that we should always consider "p" in 2pq as "1". So 2pq = 2 x 1 x 1/300 = 1/150 That means that the sperm donor's chance of being a heterozygous carrier is actually 1 in 150, not 300, because he only has to have 1 copy of diseased allele. 1/300 just mean that in a pool of 90,000 people's chromosomes, 1 in every 300 copies is a diseased copy. The rest is just like explained on above comment.

Dr. Neil, thank you so very much for these incredible videos! They were instrumental in helping me prepare for a board certification exam. I would not have had the biostatistics understanding without having step and and extra stuff. Truly, thank you for your clear explanations, problem set up and dissection of problems to identify the target within the question. You're an amazing instructor.

Watched these videos the night before each STEP and it saves me every time. Got STEP 3 tomorrow and cannot wait to be done for good. Thanks for the free points Dr. Neil!

Dr. Neil I don't even know how to begin to thank you. I had no idea what in the world I was doing on the biostats questions until I watched your videos. I have my exam next week and you're videos are gonna help make the difference. Thank you so much!!!

This is my first ever comment on youtube but these videos have been so helpful that I can't thank Dr. Neil enough. Not only are his videos amazing, but he also personally emailed me the page of notes within hours of me asking. I always thought I was bad at math but with just watching his videos one time, I was able to do very well on my class exams and i even became a TA for biostats! What makes his teaching so crucially different is the fact that he provides detailed explanations for the "simple" math after knowing which equation to use. It's simple if you have a system and he provides you that logical system you can use each time. Almost all other professors and videos speed through this part and skip steps. Thank you so much! If only we had him for he rest of the math then perhaps I could also become an expert cardio, renal, resp, and pharm calculations. #thedream

Thanks a lot! I have never seen anything as useful as this in my life. Wish you all the bests~!

I am astonished by the way you have explained biostats in lucid manner.. I incidentally came across your video while I was struggling with stats...This is superb.

Amazing videos Dr. Neil. You're amazing! I'd like to add a little trick to memorizing the +LR and -LR; Positive has P and sPecificity has P; Negative has N same as SeNsitivity and now you can remember which one to detract from 1. :D Once again, Thank you soooo much. You're a life saver.

I cant thank you enough, your videos helped me a lot in step1 and hopefully in 2 as well.Regarding the UTI and the ABC drug group question , you are given the AR and incidence of standard therapy so Incidence of exposed to the drug will be incidence of standard - AR hence 2% then instead of doing all the RR calculation if you know that if 2%of the ABC group is 29 how much will 100% be so 100*29 /2. Same thing actually but is much faster in the exam.

The second question on Hardy-Weinberg needs revisit. The answer is 1/600 but our approach needs discussion. The women is receiving sperms from a health donor and NOT a diseased. So we should calculate pq. Incidentally, because the disease is rare (p approximates 1) pq is half of q ie 1/150. Again probability of pq impregnating with q allele is 1/2. So the chances of next baby suffering from disease are 1/2x1/2x1/150=1/600.
