Building a Statistical Analysis Toolkit: Mean, Median, and Standard Deviation in PHP

30 Jul 2025

Calculate the mean: Use array_sum() to divide by the number of elements to get the mean; 2. Calculate the median: After sorting, take the intermediate value, and take the average of the two intermediate numbers when there are even elements; 3. Calculate the standard deviation: first find the mean, then calculate the average of the squared difference between each value and the mean (the sample is n-1), and finally take the square root; by encapsulating these three functions, basic statistical tools can be constructed, suitable for the analysis of small and medium-sized data, and pay attention to processing empty arrays and non-numerical inputs, and finally realize the core statistical features of the data without relying on external libraries.
