ANOVA and Data Analysis

You need to analyze our data to see if there is a significant difference due to our hydration or watering time treatments.   We will do this with 

• rosette diameter data
• fruit number data

This handout has the instructions for how to do a two-way ANOVA .  You will need the Google Sheets that are labled

• Fruit Data Analysis
• Rosette Diameter Analysis

1. ANOVA
2. Bar graph for both rosette diameter and one for fruit number
3. answers to the following questions: 
4. For % hydration: was there a significant difference in rosette diamter and/or fruit number? What was the p value (chance of being wrong)?
5. Which hydrations do you think was the best for plant growth?
6. Which hydration do you think would be the best for our purposes: to drought stress the plants without killing them. 
7. For time of watering:was there a significant difference in rosette diamter and/or fruit number? What was the p value (chance of being wrong)?
8. Does it seem like there was a watering time that was much better or worse for the rosette diameter and/or fruit number? Which one(s)?
9. Notice the interaction between % hydration and timing. What do you think could account for an interaction effect? (ie: which combination of %hydration and timing made the most difference and why do you think that was the case?)
