Beta is a measure of an investment's relative volatility. The higher the beta, the more sharply the value of the investment can be expected to fluctuate in relation to a market index. For example, Standard & Poor's 500 Index (S&P 500) has a beta coefficient (or base) of 1.

The standard top of the wall cabinet is 84 from the high point of the floor so all your wall cabinets are lined up at the top. If for example, your microwave is 16 height you can go with either a 12 or 15 wall cabinet above it.all cabinets start at 54 above the finished floor. Most OTR microwave hood combos are 16 1/2 tall. If you are lining up with a standard 84 cabinet height then the cabinet above the microwave should be 13 1/2 tall. You can go higher up with a 12 high upper cabinet but should never go lower with a 15 high cabinet.
