How to find significance of mean, Is there any formula for that.In given below table, means and standard error of means of some states are given with national mean and standard error of mean, Can we compare State mean and standarad error of mean with national?
In statistics, generally for calculating overall mean, the frequency of all the observations are considered (if the observation is repeated several times) and total number of observations is the sum of all the frequencies.
Similar approach can be utilized to obtain the overall mean here. Actually, I am talking about the approach of weightage factors. In the example you have shown here, its very clear that the average of all the 'case means' is not 247.
(239+229+244+245+245+233+260+241+248+241+239+247+250+259) /14 = 244.29
But the overall mean is 247. So, some case means greater than 247 are having a higher weightage.
I hope this might be helpful.
If you can provide your problem in a specific way, I can have a better insight.

Sir, in the same table last column is showing significance (low high and no).. how they calculated? any formula is there
