Table 1. Statistical analysis of the aquatic plant Camboba caroliniana calculated by using the

photosynthetic rates (mL O2 produced/g/hour). In a manometric system, the experimental tubes

contained ~4g of the aquatic plant and some pond water and control tubes only contained pond

water. The experimental tubes (n=4) and control tubes (n=2) were under both white light and

red light for 16 minutes with 2 minute intervals where the oxygen produced (mL O2) was

recorded. The mean represents the average photosynthetic rates, the standard deviation (SD)

indicates the variability and so, how spread apart the data was. The standard error (SE) and the

95% confidence interval (CI) represents the accuracy of how well the sample experimented with

represents its whole population.
