what is y axis in statistics vs variance of a distribution which axis represents a specific time of year when are seasonal seasonal trends measured when is variance different between a two distribution what type of test is used to test the variance of seasonality? what kind of statistical test would be appropriate to determine whether the variance of two distributions is different if the distributions are not normal? why is seasonality important to a population is the variance of a specific distribution statistically significant? how to test the variance of two distributions if the distributions aren't normal? when the range of seasonality in two geographicly isolated populations is larger than the range of seasonality of the peaks in one population is larger? how to test for seasonality of a population how to check whether variation is significant how to test the difference between a seasonal distribution and a bimodal distribution what type of a statistical test would be appropriate to determine whether these differences are significant why are seasonal seasonal patterns less significant in a population? what statistic will help determine that seasonality is significant? how to test for variation in the variance of two geographicly isolated populations of the same species? what is the difference between seasonality and variance in a given population? why is there a variance difference between two distributions of a specific species
