Type I & Type II Error, p-value, Null Hypothesis,Community Medicine tutorial,NEET PG 2020, fmge.

In this video I shall discuss about types of estimation, hypothesis testing, STATISTICAL errors TYPE I and TYPE II, p value. Estimation is the process of estimating an unknown population parameter from a known sample statistic. Hyptothesis is an assumption that needs to be verified. Hypothesis testing is the process that helps us decide whether population parameter is same as the sample statistic or there is a difference between population parameter and sample statistic. Null hypothesis does not show any treatment or association effect and alternate hypothesis shows an association or treatment effect.
Statistical errors are of two types. Type I error is when the null hypothesis is true but it is rejected. Type II error is null hypothesis if false but accepted. Type I error is more serious.
How much of an error that can be allowed is denoted by propbablity or p. Probablity denotes how much of a statistical error we can allow or denotes the evidence against rejecting a null hypothesis.
By convention it has been set as 5% or level of significance is 5%.

The same to me, I think you'd better make a playlist related to statistic concepts as those are also important for other fields like data science where I'm getting involved.
Thanks a lot. 🙏

[@rocker49963]

Mam Thank you so much for making these tough concepts understandable 🙏🏻 I had 1 doubt if anyone could help …….in conclusion mam said “smaller the p value more is the evidence AGAINST REJECTING null hypothesis”….. but as far as I can understand if p value is less than 5% results are statistically significant and in that case null hypothesis is rejected….am I getting it wrong?

[@vijayvijay-fl4xy]

Well done mam . Please taught about metaanalysis

[@drnehataneja]

Thanks...will teach meta-analysis soon!

[@siddhikakani]

Ma’am, if p value is the probability of REJECTING the Ho( meaning there is a difference between the comparing groups) shouldn’t that mean more the p value, greater will be the chances that the study we did (ie., saying that there is a difference between the 2 drugs for eg) is more significant?? But you said the lesser the p value greater is the significance of the result of the study. Could you please explain mam?

[@dr.janpreetsingh5103]

mam what is the difference between alpha and p value?

[@drsohomroy5282]

For easy understanding, BEFORE running a test suppose you estimate a probable estimation of error is called P value. Now AFTER running that test you calculated the total error is @ error (both are type 1) . So now if comes P@ = significant
