Example aspects of spreadsheets that are relevant to science education are: Using Excel as a calculator to explore, to use Excel for their own projects and future activities. Graphically displaying equations (analytical models) and real data. Obtaining numerical solutions to more mathematically complex models. Graphically comparing results from a model and observations. Statistical analysis including mean, standard deviation, error bars on graphs, linear and polynomial fits, multivariate analysis, etc. Spectral analysis (Fast Fourier Transforms).
