12 Calculating sample size and power

[yashraghuvanshi]

Can not believe that this is teaching faculty of "topmost" institute of country! Feels like a 10th grade student is reading book to me

Even after so many negative feedbacks, nothing has been done to improve upon the clarity of lectures. Very unfortunate

[remyaneelambaran]

it is really hard to answer the quiz questions only by listening to this session. please simplify and upload a video as it is a vital part of biostatistics.

[NARAYANNE]

Good lecture for those who have some strong biomed statistical basics in place

[lekshmyraj]

Some of ur classes are short and easy to understand Sir.. But some like these should be taught more clearly with examples. Cannot even answer some of the questions without mugging up the whole thing

[dramit]

What have we done to deserve these third class topics and even worse teachers😱

[tejaswi]

I have been hitting my head to understand this

[Vinayakasu]

No clarity not even confident, just confusing, not even got answers in this video, plz sir improve ur teaching skills

Issuing an order to give bcbr exams suddenly after all these years, asking for money from students all over india, and what do you do in return? Upload such videos of incompetent professors who cant even say a word other than what is written in slides. Seems like this man wanted to teach history rather than statistics, trying to make students mug up everything as he must have done the same back in those days. Have Shame and replace him.

[MrFilu]

Thank you sir..at time 13.40, the most valuable information I found, for the first time.. wonderfulyl explained

[dr.nitinjl]

In lecture 8 it was told that Precision is reproducibility and Validity is closeness to true value, not in this lecture Precision is closeness to true estimate teach

[naitiksinghchauhan]

Kuch samajh nahi aya bhai, please provide more examples in steps and be clear

[suganyaezhilarasan]

Thank you sir. It was informative definitely

[drpoonamgupta]

Read twice ...could not understand.
What to do?

[cestovatelekar]

You taught calculation considering we are already prepped with it. My stream of education just got this injected that i had no clue i would ever get back in to.
How come confidence coefficient 0.95 to become z - 1.96 ?

[mohammeddanish]

worst lecture of nptel
no clarity plz put some effort in explaining this part as it is important topic and the reader just brushed through it casually

[DrSamneet]

Pls improve your teaching, highly unsatisfactory.

[mohansaikrishna]

Just reading slides... explanation needed with good examples...not well explained

[DashWatson]

Very poorly explained. Just glossing over the topics superficially rather than in depth.

[hakfhsjakhfjksah]

We can't solve the mcq by watching this video. Couldn't understand anything.


This ones much better!
