If the data is sorted from smallest to largest, the minimum is the first value, the median is the middle value, and the maximum is the last value. If there are an even number of data points, the median is the average of the two middle points. The median divides the population into two halves. ojt教育とは介護WebWith the SymPy package this gets replaced by a more julia n syntax: using SymPy x = symbols ("x") # or @syms x y = sin (pi*x) y (1) # Does y.subs (x, 1).
