Take the observation of an approximately exponential decay of some "thing" over time. Pick the value of the number of things you had when you started making the observation. Scale your subsequent observations by the initial value. By eyeball pick a timescale over which the ratio is really much smaller than one, and scale your observation time by that amount. Now plot thing-ratio to time-ratio and fit an exponential curve. The timescale you eyeballed divided by the dimensionless exponent from your curve fit gives you the decay time constant of the process.
Logarithm is inverse. So rotate and flip your graph paper around. We teach this kind of thing in freshman physics labs.
