Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question because one anticipates variability in students’ ages. .

We count pollination events on a set of flowers to estimate visitation frequency.. Many natural (physical) phenomena exhibit . variation. = one quantity (quantities) changing on account of another (or several) . Principle is some kind of dependence. What things can we think about that depend on another action/object? . News. Looking at Normal Distribution and Its Familiar Curve. Using Measures of Data Variation to Judge the Credibility of Statistics in the News. Just as you can use measures like the margin of error and standard deviation to gauge your confidence in the data that you’re reading, you can also use these metrics to measure your confidence in the articles or stories where the statistics are reported. . to .

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:. What is variation?. Define Variation…. What controls variation in a population?. Most characteristics are controlled by multiple genes. Any character that shows a gradation from one extreme found in the population to the other is called . 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. . Arts and Leisure. Athletic sports, dancing, decorative art, games, music. Basic Needs.

Direct Variation. y varies directly as x if there is a nonzero constant, k, such that . y = . kx. *k is called the constant of variation. Plug in the two values you have and solve for the missing variable. SOL A8. by Robert Lotze, Moody Middle School. Direct Variation. The longer you shower, the more water you use..
