Does that mean we must accept the incorrect result with the given district rank?

Formula used in determining Z score is wrong, whenever a combine mean is taken Z score is wrong. That is not a z score, it is only a mess. That is the reason why all the results in 2011 and z scores were wrong. There is a standard internationally accepted methodology and formula for Z score analysis.Advance level results should be released on Z score. 2011 results are not founded on Z score, entire results are prepared on an erroneous equation. Entire A/R results are incorrect due to the use of wrong formula.
