If the data points were measured on uniform intervals you could use Fourier transform methods as described in The Mathematica Journal Vol 8.3 pp 383-387. Alternatively, you could use Interpolation to construct an interpolating function and take the derivative of that. Note, before using Interpolation you will want to smooth the data in some way.
