Step 7. To mark the stair railing, hold it in place, resting along the stairs, and mark it for the angled cut. Pre-drill the landing and treads for the balusters, using a special stair bit that drills the hole and then creates a thread to accept the baluster bolts.
What is interpolation? Interpolation is the process of estimating unknown values that fall between known values. In this example, a straight line passes through two points of known value. You can estimate the point of unknown value because it appears to be midway between the other two points. The interpolated value of the middle point could be 9.5.
Interpolation and Extrapolation. A hypothesis can be used to predict the results of observations or the existence of other phenomena. There are two types of predictions that can be made.One is called extrapolation; the other is called interpolation.In the next paragraph, examples of both are provided. Extrapolated predictions are those that are made outside of the known data points.rends in the known data can often be used to make accurate extrapolated predictions; however, this is not always the case. A young man's parents kept track of his height through the years, as shown in the graph below. Extrapolation shows that Bryan will be about 10 feet tall when he's 30 years old.
