WebThat equation will have a fixed mean and standard deviation, and taking more and more samples simply gives you more confidence in your estimate of the mean and standard deviation. As far as the variation in the experimental program, think if it this way.

If the statistic is the sample mean, it is called the standard error of the mean (SEM). The sampling distribution of a mean is generated by repeated sampling from th…
WebMar 26, 2016 · So you would report your mean and median, along with their bootstrapped standard errors and 95% confidence interval this way: Mean = 100.85 ± 3.46 (94.0–107.6); Median = 99.5 ± 4.24 (92.5–108.5). You’ll notice that the SE is larger (and the CI is wider) for the median than for the mean. This is generally true for normally distributed ...
