Population Parameters
The previous page outlined the sample statistics for diastolic blood pressure measurement in our sample. If we had diastolic blood pressure measurements for all subjects in the population, we could also calculate the population parameters as follows:
Population Mean
Typically, a population mean is designated by the lower case Greek letter µ (pronounced 'mu'), and the formula is as follows:
where "N" is the populations size.
Population Variance and Standard Deviation
The corresponding equations for the population variance and standard deviation would be the following (
is the lower case Greek letter sigma):
