A researcher wanted to explore whether fish abundance in tropical coral reef systems differed significantly between the cyclone and non-cyclone seasons. To conduct this experiment, underwater visual census surveys to count the number of fish present were conducted at twenty different coral reef systems during both the cyclone and non-cyclone season of a given year. What type of statistical test should be used to determine if there is a difference in seasonal fish abundance; ANOVA, paired t-test, 1 sample t-test, or a 2 sample t-test?
