**drwls**, Tuesday, October 30, 2007 at 12:46amFor those samples, the rate is 19.2% for men and 16.7% for women. A higher rate for men is likley but no proven. You must also consider the sample size and standard deviation.

If the male illiteracy probability were 19%, the expected standard deviation in the number of illiterate men in a sample of 234 would be

sqrt(0.19*0.81*234) = 6.0, and for women in 251 cases it would be sqrt(0.17*0.83*251) = 6.0 also. This means the reported male illiteracy rate has a standard deviation of 2.6% and the female rate has a standard deviation of 2.4%. Think of these as the probabe errors in the measurement.

The separation of the two illiteracy rates is only about one standard deviation, so the findings do not have a high degree of statistical significance.
