A population data set is a data set that includes all members of a specified group. Required fields are marked *. The empirical rule states that for most normally distributed data sets, \(68\%\) of data points are within one standard deviation of the mean, \(95\%\) of data points are within two standard deviations of the mean, and \(99.7 \%\) of data points are within three standard deviations of the mean. Discrete quantitative variables are quantitative variables that take values that are countable and have a finite number of values. There are similarities in both categorical and quantitative data that are worth getting to know. The term discrete means distinct or separate. Have a human editor polish your writing to ensure your arguments are judged on merit, not grammar errors.
