The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. If the parameter or the statistic is the mean, it is called the standard error of mean. The following expressions can be used to calculate the upper and lower 95% confidence limits, where x  getcalc.com's Standard Error (SE) of mean or proportion calculator to to solve standard error worksheet problems online by using standard deviation or without

Many people believe that they can't do anything to protect their privacy online, but that's not  2. Normal approximation to the binomial calculation: Standard error of the mean = SEM = √x(N-x)/N3 = α = (1-CL)/2 = Standard normal deviate for α = Zα =. The margin of error is the amount of error that you can tolerate. If 90% of respondents answer yes, Online surveys with Vovici have completion rates of 66%!  Calculate the approximate sample size required to obtain a desired margin of error using Standard Deviation from a sample population (aka Standard Error),  

Determine the standard deviation of the original distribution. The standard deviation simply tells us how far apart the numbers are on the number line. The information may be provided to you if you are working out a statistics problem. If so, replace the σ in your formula with the standard deviation. If it is not provided, you will have to find it on your own.
