When the ratio of two variables quantities varies the relationship is called a direct variation?
The statement is incorrect; a direct variation occurs when the ratio of two variables remains constant, meaning that as one variable increases, the other increases proportionally. In contrast, when the ratio of two quantities varies, it indicates an indirect or inverse relationship. In such cases, as one variable increases, the other decreases. Thus, direct variation implies consistent proportionality, not variability in the ratio.

When two quantities form a direct variation what is it called?
A direct variation (!) or direct reelationship.

What are the letters in an equation called?
The letters in an equation are called variables. They represent unknown values or quantities that can change. In addition to variables, equations may also include constants, which are fixed values. Together, they help express relationships between different quantities in mathematical expressions.

How do you explain the analysis of variance assuming that your audience has not had a statistic class before?
The measurement of any statistical variable will vary from one observation to another. Some of this variation is systematic - due to variations in some other variable that "explains" these variations. There may be several such explanatory variables - acting in isolation or in conjunction with one another. Finally, there will be a residual variation which cannot be explained by any of these "explanatory" variables. The statistical technique called analysis of variance first calculates the total variation in the observations. The next step is to calculate what proportion of that variation can be "explained" by other variables, and finding the residual variation. A comparison of the explained variation with the residual variation is an indicator of whether or not the amount explained is statistically significant. The word "explain" is in quotes because there is not always a causal relationship. The causality may go in the opposite direction. Or the variables may be related to another variable that is not part of the analysis.
What is a relationship between two variables or sets of data is called what?
