WebbIt turns out that examining whether or not error bars overlap tells you less than you might guess. However, there is one rule worth remembering: When SEM bars for the two groups overlap, and the sample sizes are equal, you can be sure the difference between the two means is not statistically significant (P>0.05). WebbThe usual sample sd for 0,1,1,1 is 0.5 rather than 0.433 (they differ because the binomial ML estimate of the standard deviation p ^ ( 1 − p ^) corresponds to dividing the variance by n rather than n − 1 ). But it makes no difference - in either case, mean + sd exceeds the largest possible proportion. kyam maher mlc kya meri sonam gupta bewafa hai wiki
