Cast your ballots for the SAS Support Communities, nominated for the Khoros Kudos Award: Best-in-Class: Community.
Many nonparametric statistical methods use the ranks of observations to compute distribution-free statistics. In SAS, two procedures that use ranks are PROC NPAR1WAY and PROC CORR. Whereas the SPEARMAN option in PROC CORR (which computes rank correlation) uses only the "raw" tied ranks, PROC NPAR1WAY uses transformations of the ranks,
SAS® CodeSnaps is an easy, affordable, and engaging tool. All you need is one iPad, the free CodeSnaps app, one Sphero robot, and a problem to solve. Students work collaboratively in teams to generate the code required to move the Sphero; they build a program using the printable coding blocks, scan it with the app, and execute the program to check their logic. CodeSnaps is accessible and appropriate for all learners across all disciplines. Get creative and challenge your students to navigate an obstacle course, find members of a word family, explore the digestive system, or travel the Oregon Trail. Your imagination is your only limitation.
