Data analysis in Excel

Excel is a common tool we use it very frequently. But some power functions are hidden inside until we mine them out. (I will keep this post updated.)

FREQUENCY function [1]

“this useful function can analyse a series of values and summarise them into a number of specified ranges.” Or in a simple word: frequency distribution. Once you have the distribution, you can draw Histograms[2] to show it.
