Though the northernmost islands experience a bit of rain, September is largely dry, warm and sunny throughout the islands. High season in Hawaii doesn't start till mid-December, so September is still off-season for the Hawaii tourism industry and deals abound.
T-tests and analysis of variance (ANOVA) are widely used statistical methods to compare group means. For example, the independent sample t-test enables you to compare annual personal income between rural and urban areas and examine the difference in the grade point average (GPA) between male and female students.
DEFINITION of 'Analysis Of Variance-ANOVA'. A statistical analysis tool that separates the total variability found within a data set into two components: random and systematic factors. The random factors do not have any statistical influence on the given data set, while the systematic factors do. The ANOVA test is used to determine the impact independent variables have on the dependent variable in a regression analysis. Next Up.
