Hello, I wanted to know if ANOVA works out when it comes to prove independence between variables. Particularly, I am studying how several conditions regarding an industrial process (such as temperatures and flows) affect one of the chemical components of the product. I know that the dependent variable would be the amount of the chemical component and that the process conditions would be the fixed factors. But how can I interpret the interaction between this variables (and the combination of them) with the chemical component with the ANOVA results?

Thank you in advance!

Beside the professional statistical software Online statistical computation , and the use of a scientific calculator is required for the course. A Scientific Calculator is the one, which has capability to give you, say, the result of square root of 5. Any calculator that goes beyond the 4 operations is fine for this course. These calculators allow you to perform simple calculations you need in this course, for example, enabling you to take square root, to raise e to the power of say, . and so on. These types of calculators are called general Scientific Calculators. There are also more specific and advanced calculators for mathematical computations in other areas such as Finance, Accounting, and even Statistics. The last one, for example, computes mean, variance, skewness, and kurtosis of a sample by simply entering all data one-by-one and then pressing any of the mean, variance, skewness, and kurtosis keys.
