Answer 2

correlating
extrapolating
interpolating

Answer 3

Do you know the difference between extrapolating and interpolating?

Answer 4

no

Answer 5

Basically, interpolation is when you want data that is between two points that you already know. Here, we have values for x = 1, 2, 3, 4, 5, 6, 7, and 8.

Answer 6

So if we wanted data within that range but that wasn't at exactly one of those values, we'd have to interpolate. 15, though, is outside of the values.

Answer 7

That means we need to *extra*polate. Extra means beyond, outside of (thus, extra credit, credit beyond what you usually get). So it means to take existing data and try to figure out the values outside of the range in which you actually have measurements.

Answer 8

The last one, correlation, means taking two different types of data and figuring out how they're related. It's completely irrelevant in this case :)

Answer 9

ok so it would be correlating then the first one
