The function stdevp is specifically designed to calculate the population standard deviation, which is appropriate when you have access to the complete set of data for the entire population you are analyzing. This function takes into account all data points in the dataset and measures how much the values vary from the average of the entire population.

In contrast, the stdev function is used when you're working with a sample of data rather than the entire population. It calculates the sample standard deviation, which adjusts for the fact that you're using a subset of the entire population. The calculation incorporates a correction factor because the sample may not fully represent the population, leading to different results.

By using stdevp, you are determining the spread of values considering all the available data points in the population, which gives a more accurate representation when the entire dataset is known. This is crucial in statistics, as the choice between population and sample functions can significantly affect the conclusions drawn from your data.
