JMP Data Files

NOTE: All files on this page are in JMP file format.  They can only be used with the JMP-IN software.  This software is available in the BSCI 111 lab as well as on all of the other campus computer labs.  It is NOT available for free download off of the Internet.

Practice data (NOT required for the problem set):
Ten vireo eggs from Ontario were weighed and ten vireo eggs from the southeastern US were weighed.  Type of data: continuous.  Comparison: group means.  Appropriate test: t-test of means.  Null hypothesis: the mean of Ontario eggs is the same as the mean of SE US eggs.

Example of contingency test from a previous lab:
The number of individuals that were colonized and were not colonized by ants were counted for two different species of Acacias.  Type of data: counts.  Comparison: whether an outcome (being colonized by ants) was more closely associated with one group (Acacia species A) than another (Acacia species B).  Appropriate test: chi-squared contingency test.  Null hypothesis: there is no association between being colonized and being a member of species A (or B).
