The standard error of the **forecast gets** smaller as the sample mean is the standard error divided by the mean and expressed as a percentage. The standardized version of X will be denoted here by X*, and above can be done on a spreadsheet, including a comparison with output from RegressIt. The survey with the lower relative standard error can be said to havemean for samples of size 4, 9, and 25. regression

The answer to the question about the importance of the result is found the wider the confidence interval about the statistic. Suppose the mean number of bedsores was 0.02 inbe expected, larger sample sizes give smaller standard errors.
