Standard Deviation of an entire population is known as σ (Sigma) and is calculated using the square of the difference between each data point and the population mean, finding the sum of those values and then dividing The standard error of the proportion is defined as the spread of the sample proportion about the population proportion. More specifically, the standard error is the Standard Errors and Confidence Intervals Introduction In the document ‘Data Description, Populations and the Normal Distribution’ a sample had been obtained from the population of heights of 5-year-old boys. percent confidence band or “95 out of 100 chances” for the 95 percent confidence band. Obviously the increased levels of confidence would expand the range of scores included in the probability statements.
