The Problem:. People often wish to jump to the conclusion that a trait. . change . they see is the result of adaptation. However. , that is not always the case. There are other mechanisms that could cause phenotypic variation. For use with Chapter 4 of:. Galloway, N. and Rose, H. (2015). . Introducing Global Englishes. . . Routledge. .. © Dr. Heath Rose and Dr. Nicola Galloway. Review of Lecture 3. There are many advantages to having a global lingua franca – increased . Goal: Use inverse variation and joint variation models.. Warm-up. Simplify:. Inverse Variation. 2 variables, x and y, vary inversely if:. k is called the constant of variation.. Example 1. Tell whether x and y show direct variation, inverse variation, or neither:. Section 5-2. Goals. Goal. To write and graph an equation of a direct variation.. Rubric. Level 1 – Know the goals.. Level 2 – Fully understand the goals.. Level 3 – Use the goals to solve simple problems.. What do you mean by variation..?. Differences between species. Differences within a species. SPECIES : .

When a problem states that variable X varies directly as variable Y, we know that the relationship implied is . . X = . kY. And that the first step in solving the problem is to find the value of the constant of proportionality k. . SOL A8. by Robert Lotze, Moody Middle School. Direct Variation. The longer you shower, the more water you use.. You can describe this. Relationship using. . Direct Variation. The Direct Variation . . y = . kx. , where k ≠ 0. . The constant of variation for a direct variation . k. is the coefficient of . x.. Example of direct variation. : The time it takes to hear thunder varies directly with the distance from lightning. (As the distance from lightning increases, so does the time it takes you to hear the thunder!). How do animals learn. Why?. What?. Sheehan and Tibbetts, 2011. Individual Learning. Shettleworth.

Phenotypic . factor analysis. A statistical . technique to investigate the dimensionality . of correlated variables in terms of common . Introduction. Population mean . gives no idea about the phenotypic values recorded on different individuals whether values are same or different.. If values are same or similar, then population mean also will be the same. If values are different from individual to individual then population mean cannot tell about the distribution of values around the central value, the population mean.. Human variation: defined . Human variation refers to the fact that there are a range of possible values for each of the numerous physical characteristics of human beings.. People of the same species can have differing phenotypic traits that can be related to:. Paul VanRaden and Jeff O’Connell*. Animal Genomics and Improvement Laboratory.
