Very useful lecture. Thank you very much sir for uploading this video. Now I understood which formula to apply to calculate a sample size in different interests. However, I expect more from you sir, specially why confidence level is always 95% and power is always 80%. I I am expecting your explanation in another video. Thank you once again.
PLEASE SOLVE FOLLOWING QUESTION STEP BY STEP : In a cross-sectional study, a group of researchers wanted to estimate the prevalence of cephalosporin-resistant E.coli among adult males with urinary tract infections. From previous literature, the prevalence was found to be 6.5%. If the researchers want to estimate the prevalence with a 20% relative precision and 95% significance level, what is the minimum sample size required?
With due respect to speaker...it's not at all understandable for non PSM person. Not able to understand, let alone solve assignment after the lecture..why u keep doing this...plz give teaching work to people who can teach🙏🙏🙏
In the analytic study calculation it should be (0.25 -0.15 ) square ... at at 22 mins 20 seconds time. Again same mistake in second example (0.18-0.10) plz correct it
Speech of the speaker is not uniform. Almost in audible at the end of each sentence. Has skipped important points that non PSM students can never understand and it is difficult to answer the assignments. Has rather emphasised on unnecessary topics
No disrespect Sir but it is very difficult to understand what is being taught. In the end we just mugg up things and vomit it out, failing the whole purpose of this course.
wrong calculations everywhere and YOU PEOPLE EXPECT MEDICAL PGS TO WATCH THESE VIDEOS AND GIVE ASSIGNMENTS OTHERWISE NO FINAL YEARS. HAVE YOU GOT NO SHAME?????
Thank you so much, Professor Ramakrishnan.

Maan karta hai goli marduu inn module walo gazab chutiyapa laga liya hai….
How can we calculate sample size from mcid number? How can we get mcid number for any outcome measures?
Sir how to calculate sample size for a pilot population from a given larger population whose sample size we already know
Nice lecture

But final ans. Is correct sir
Anyway your observation is very keen sir , wonderful 👍
Nice explanation sir

Need easy explanation….difficult to grasp and understand concepts
