The function that specifically targets the population variance is indeed varp. This function computes the variance of a set of values while treating the data set as the entire population, rather than a sample. This distinction is crucial in statistics, as the calculation of population variance differs from that of sample variance due to how the degrees of freedom are handled.

When calculating population variance, the formula divides the sum of the squared deviations from the mean by the total number of data points. This is what varp does, providing an accurate measure of how much a set of values varies within an entire population.

In contrast, functions like var would calculate the sample variance, which involves dividing by one less than the number of observations, thus adjusting for the bias that can occur when estimating variance from a sample rather than a complete population. Similarly, while stdev and stdevp relate to standard deviation, they too serve different purposes—stdev for sample standard deviation and stdevp for population standard deviation.

Understanding these distinctions can aid in proper data analysis, ensuring that the correct function is utilized based on whether you are working with population data or sample data.
