Introduction Introduction Key Question: Will water variation affect the  growth of corn? Hypothesis: Variations in water will affect the  growth of corn. Prior Knowledge: Salts reduce plant growth.  (Henry-PSS 4316) Initial response of turf to  salinity is reduced shoot growth. (Henry-PSS  4316)

Unformatted text preview: T-test Results Results Results Control Group Final Mean Growth: 30.667cm Experimental Group Final Mean Growth: 15cm Personal Observations: The control group grew while experimental growth was inhibited and stopped by the use of salt water Conclusions Conclusions Hypothesis: Variation in water will affect the growth of corn. The data supported the hypothesis because the experimental groups average growth was less than that of the control group as indicated by weekly measurements, mean growth measurements, and t-test values. Comparisons Comparisons Control Group Experimental Group Data Analysis Mean Growth 18.70818 10.02727273 Final Mean Growth 30.667 15 T-test 0.033768 As indicated by the values above we accept our hypothesis.
