The experiment was designed with three-test groups and one control group, each group containing ten seeds. The control group used only pure water to wet the seeds whereas the experimental groups used 25%, 50%, and 100% solutions of ethylene glycol. The seeds were placed in adequately watered and lighted petri dishes that were lined with filter paper (to retain the water). Each was monitored over a 72 hour period; at the end of this time, the data was collected concerning the hypocotyl and epicotyl lengths of the plants. Using either Excel or the TI-83 graphing calculator, perform an ANOVA on the hypocotyl data to determine if there is a significant difference in the length of this structure among the plants grown at varying concentrations of ethylene glycol. If there is a significant difference, you will need to determine the means that are significantly different by doing a Tukey Test. Following the same procedure, complete an ANOVA on the epicotyl data as well.

This data exists in three files; one is in Excel Data format, one is in Text format, and one in TI-83 Group format. If you want to perform the ANOVA using the TI-83, you will have to import the text data into the calculator from the computer after you have downloaded the file.
