Q4_2_d:There was a significant difference between the population mean number of barnables recruiting on the algae covered surfaces and the bare surfaces. No significant differences were found between algae type or between naturally bare and scraped bare surfaces.
Q2_1:Although there are two outliers, there is no evidence of non-normality (skewness) and the spread of data (variances) appear homogenous between groups (no relationship between mean and variance).

Q4_3a:With the global ANOVA we are testing the null hypothesis that all the population group means are equal. Additionally, we wish to test a specific null hypothesis that the population mean larval richness in long hydroperiod wetlands with fish is equal to that of the population mean larval richness in long hydroperiod wetlands withou fish.

Q4_5:Statistical - Reject the null hypothesis that population group means are equal, and reject the more specific null hypothesis that the population mean larval richness in long hydroperiod wetlands with fish is equal to that of the population mean larval richness in long hydroperiod wetlands withou fish. Biological meaning - Hydroperiod was found to have a significant affect on larval amphibian richness. Within perminant wetlands, the presence of fish significantly reduces the richness of larval amphibians.
