these formulas. Let’s find the sum, average, and median of all salaries. You can find all salaries between the J2 cell and the J1001 cell. Although we can calculate these values using Python, we will use the Excel formula “=SUM(J2:J1001)” to show you how to automate Excel ...
You can apply Python statistics functions and methods to it just as you would to 1D data: Python >>> np.mean(a) 5.4 >>> a.mean() 5.4 >>> np.median(a) 2.0 >>> a.var(ddof=1) 53.40000000000001 As you can see, you get statistics (like the mean, median, or variance) across...
