(Particle sizes for Danish sediments)

Sediment particle size data from 6 size ranges at 3 sites (A, B, C), at 2 depths (2m and 5m), and 5 replicate samples from each site/depth combination are in C:\Examples v7\Denmark PSA\ Denmark PSA histogram. The data are already standardised to % composition – if not, you would need Pre-treatment>Standardise>(Standardise•Samples)&(By•Total). So, take Pre-treatment>Cumulate Samples>(Variable Order•As worksheet). The variable labels are now inaccurate, so replace them by copying/pasting cumulative from Edit>Indicators and into the Edit>Labels>Variables dialog.
