The eurypterid-bearing strata are in the lower part of the quarry and are now covered by scree. The number of factors was based on eigenvalues >1 and on a scree plot. The scree plots pointed to a three factors solution. A scree plot was used to determine the numbers of factors to be taken into consideration. A scree plot demonstrates a downward kick in the curve of variance explained after the fourth factor. After examining the hierarchical tree diagram (or dendogram) and the inverse scree plot, a six cluster solution appeared to provide the optimal solution. Using dual criteria of the scree plot and eigenvalues greater than one, analyses of the 10 attributes in question indicated a two-factor solution. Scree allowed retention of two factors, only one of which was reliable. The scree test was used to determine the number of factors to be extracted. Three components were produced based on eigenvalues greater than 1 and the scree plot confirmed the meaningfulness of the three components. A scree test was used to identify the number of factors. Scree plots of eigenvalues indicated the emergence of two clear parental factors, consistently across settings. Most colonies are located well inland on nunataks - small outcrops of barren rock and scree surrounded by glaciers - with very little other avian and mammalian life. Scree plots and parallel analysis were used to determine the appropriate number of factors to extract. These examples are from corpora and from sources on the web.
