Question

Which series of data is best suited for a logarithmic chart?

Answer 1

A) 1, 2, 3, 4 . . .
B) 2, 4, 6, 8 . . .
C) 1, 4, 9, 16 . . .
D) 1, 3, 9, 27 . . .

Answer 2

Ideally, y = ax^n

log y = log a + n log x

so C with y = x^2 looks best

Answer 3

D appears to be \(y=3^x\) which fits best of all. Nice straight line on a log graph.
