## Topic: Use IF Statement

Problem

In studying financial markets, it is helpful to identify periods when the stock markets move in a certain fashion.  Take the Nasdaq composite index, for example. Suppose we download its monthly data for the last twenty year.  We can compute its monthly changes during each month.  If the combined change of the current month and its previous two months (i.e. three-month total) exceed 300 points, then we call the market is “upbeat”.  If the three-month total drops more than 300 points, then we call the market is “downbeat”.  Identify those upbeat and downbeat months.

Use COUNT and COUNTA to compare the number of surveys received against the total numbers recorded.  Then use COUNTIF to calculate how many customers gave out scores higher than 80.
