Proportion of variance plot. This graph is similar to the Scree Plot described above, but is used with a slightly different interpretation style.

Biplots are combinations of score plots and loading plots. Loading plot provide a means to visualize the coefficients for two selected principal components. Score plot provide a means of viewing the original data in the new (reduced) dimensional space of two indicated PCs (typically PC1 as the horizontal axis and PC2 as the vertical axis). Scree plot are used to visualize raw eigenvalues for each principal component (PC) identified in principal component analysis (PCA). Prism will automatically encode categorical text variables into numeric “dummy” variables.

Automatic variable encoding – Enter your data and let Prism take care of the rest.

“1”, simply enter “Male” and “Female” directly in the data table. Instead of coding a variable like “0” and

Text information in the data table – Enter data directly as text.

Increased data limits – enter up to 1024 columns of data in each data tableĪutomatic identification of variable types – Identify variables in the Multiple variables data table asĬontinuous, categorical, or label values.

Explore larger data sets using a standard structure, and perform new and improved analyses with the following improvements: Prism 9 introduces a number of great improvements to the Multiple Variables data table. GraphPad Prism 9 – Data on a higher dimension!
