- Krejcie - Morgan Formula for Sample size Calculation:
The ever increasing need for a representative statistical sample in empirical research has created the demand for an effective method of determining sample size. To address the existing gap, Krejcie & Morgan (1970) came up with a table for determining sample size for a given population for easy reference.
I have explained Krejcie and Morgan calculation in a simple and easy way.
lucid presentation... highly inforamtive...
How do u know the chisquare?
Thank you. I would like to refer to this and put into my innovation work.
Ok

Useful sir.. Thank you
Very simple presentation. But Sir, i have a confusion that sample size will be calculated for the whole population as N or pollution of different cities will be calculated separately and then added to get sample size?
Hi sir, can we use margin error 7% and is there any journal that refers it? Thank you
is this applicable for population size of 316 stdudents?
thank you very much for this simple way of demonstration
Sir if 1500000 is population means what is sample size
Based on the calculation, It could be 384 (s) as your sample size. However, you may give it a try to solve it by your own 👍🏻
If sample size is 1786514 then what will be sample size?
It seems like you're asking for the sample size given that it's already provided as 1,786,514. In this case, the sample size would still be 1,786,514. If you're asking for something else, could you please clarify?
if the population size is 1,786,514 and you want a sample that represents it with a 95% confidence level and a 5% margin of error, you'd need a sample size of about 385.

I think the X^2 in the denominator should be 3.841^2 and not 3.841 per the formula above. (2.46 minutes of the video)
Thank you!
nice
very helpful. pleases can u use 3.5million .. i'm a little confused
can someone answer this, is this formula more credible than any other method like slovin etc, becaus im still confused What are the advantages of using this formulas?
Even when I practically calculate the sample size ,I don't the same values in the table
would you please reply to my comment, I would like to determine the sample size for a given grade among schoolchildren in a given school
so from your video:
I should ask the responsible (teacher or headmistress) about the number of students in all classes (for example, 8 classrooms of the specified grade with total students number= 240)
and what about the population proportion? (I am searching for the knowledge and attitude assessment among these students towards certain issue.)
could I assume that it is 50%
and I will use:
confidence level 95% at which the z score= 1.96
and error 0.05
Generally it is taken as 50 percent
Slovin formula is much easier and is more accurate
