This channel is dedicated to providing free lectures in courses to students who find normal lectures boring. I try to portray conceptual and example-based learning as it can help remember concepts.

Need ppt or pdf file
Thank you sir 😇🙏🏻
Thanks for the priceless videos. Could u pls share the pdf of the textbook
Hi unfortunately I don’t have the pdf. I think you can find it if you search online. It’s called Holt Physics.
Sir, can you please share a pdf of your videos?
This man can explain very well the work that was confusing me ever. Thanks 🙏
Wonderful explanation sir thankyou 😊
Very nicely explained. Thank you so much !!!
He has made me understand better than my university lecturer thank you ❤
Makes sense
good
If N is greater than or equal to 30 we use z formula not t formula. But your videoes are good I am learnming
Thanks
❤❤❤❤
Ur class excellent explanation sir
Thanks and welcome! Please like, share and subscribe!
Which book you have prepared? Sir
Hi James, Please find the link for the book below: archive.org/details/BIOSTATISTICS
Wow
Thank you
thank for this informative lecture:). However I want to point out that in minute 46:04 you answered 92th percentile by finding the closest integer less than the value of np\100 and stopped there making the answer 18th instead you should add one to the closest integer less than the calculated value which was defined in the book as k..so the correct answer is actually 19th and not 18th...in other words you should be taking the ceiling function for the non integer value
@NoulElzogheir yes I have overlooked a mistake and I will highlight your comment and add the edits soon. Thank you for noting and commenting.
Kindly I have these questions: *Is there is an exam for it internationally to be certified? *Is it nessasary to have this topic along with epidemiology. *I am interested to do master in public health , is it enough to do biostatistics and epidemiology .
Hi zohal, Yes Biostatistics and Epidemiology and important topics to be studied for a student of masters in public health. Biostatistics forms the core knowledge for application in Epidemiology. Yes you can search online for certifications.
Thanks alot u reply clear all my doubts for understanding this topic
It's my pleasure

Hello sir, I didn’t understand how to solve the question you’ve given for solving in last part of Binomial.
We’ve n, p, q values as 20, 0.24, 0.76 so I’ve calculated expected value as 4.8 and variance as 3.648 but not able to interpret the given data
in the last problem can we use direct formula for PPV as D/T and for NPV as D-/T- instead of using with sensitivity and specificity?
Then it wouldn’t account for prevalence and it would account for 100% prevalence of the disease.
Okay so we’ve to calculate for prevalence calculated from given data
Thanks for your valuable lecture. Can we use use excel instead of software
Surely! I will try to make it with excel in the future.
I’ve one doubt once we calculate SD value, that value what does it indicate? Is it e.g SD=4.9, means there is variation of data of 4.9 around mean value?
Certainly! Standard deviation shows how spread out or closely packed numbers are in a group. A high standard deviation means the numbers are more spread out, while a low standard deviation means they are closer to the average. It helps you understand how consistent or varied the data is. If the standard deviation is 4.9, it suggests that the values in your dataset are, on average, about 4.9 units away from the mean. This indicates a moderate amount of variability or spread in the data. In practical terms, it means that individual data points tend to deviate from the average by around 4.9 units.
Thank you 🙏🏻
Very helpful

Great work. Though you made a mistake when calculating the 25th percentile. Instead of getting the average that is dividing by two you divided by 100. It might be a typing error because the answer is still correct

Dear Sir, profound thanks for your prolific lectures. How much power is usually acceptable
Usually 0.8 and above but most research is around 0.4
Many Thanks for your enlightening videos. I would like to know on what basis the alpha value is calculated?
Alpha value is generally taken as 0.05 as per literature but it depends on the research and significance being tested. To find the actual alpha error we can calculate the P-value.
Im a new college student and I've been looking for a video that would help show a more in depth explanation from this textbook. This is really helpful!!

Sir but what if you are given 96% as your confidence interval
Most commonly 96% are not used. If you would like to calculate them you can use the normal distribution table to calculate the z-value at 0.96 and use that value in the confidence interval formula instead of 1.96 if it is a one tailed test. If it is two tailed test you can find the z value at 0.98 and use that value instead of 1.96. I hope that answers your question.
Its a great lecture,but the slides are blurred can you fix this please.tnx.
Thank you for the feedback. The blur might be due to buffering. Please try with better network coverage and see if that helps.
very good explaination
