A frequency polygon graph in Excel is a useful way to represent the frequency of different observations. For example, if you own a business and count the number of customers you have each day for 30 days, you end up with a series of numbers that can be hard to interpret at first. However, if you separate the observations into groups, such as 0 to 9 customers, 10 to 19 customers, 20 to 29...
