WebStep 1: Calculate the mean of the data—this is \mu μ in the formula. Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations. Step 3: Square each deviation to make it positive. WebConsider now the mean of the second sample. If the sample comes from the same population its mean will also have a 95% chance of lying within 196 standard errors of the population mean but if we do not know the population mean we have only the means of our samples to guide us.
