An experiment is a controlled test or investigation.
Linear extrapolation uses a subset of the data instead of the entire data set. For this type of data, it is sometimes useful to extrapolate using the last two or three data points in order to estimate a value higher than the data range.
Linear interpolation uses a straight line to connect the known data points on either side of the unknown point. It can be considered as filling in the gaps of a table of data.
A survey is a data collection method used to gather information about individuals’ opinions, beliefs, or habits.
