PPT-11.1 Measures of Center and Variation

What We Will Learn Compare mean median and mode Find range and standard deviation Identify effects of transformations on data Needed Vocab Measure of center mean median and mode Mean sum of the data divided by total number of data values aka average. Mean, Median, Mode, . Range. Measures of Variation. Box . Plots. Line . Plots. Histograms. CCGPS Standards. MCC6.SP.1. . 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. . 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. . 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 : . A . species.  is a group of organisms that are able to interbreed and produce . fertile.  offspring.. Arts and Leisure. Athletic sports, dancing, decorative art, games, music. Basic Needs. Clothing, cooking, housing. Beliefs. Folklore, funeral rites, religious ritual. Communication & Education. Education, language. 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. Liz Cirulli. Assistant Research Professor. Duke Center for Applied Genomics and Precision Medicine (CAGPM). 4/27/15. Advantages to studying healthy variation. Most “healthy” traits not studied genetically at all. 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!). 1. Attributes of Common Cause Variation. It is the variation inherent to a Process.. It cannot be reduced unless one changes the Process.. It can be considered to be the background noise present in a Process.. 1(a) paned o de; 1(b) panad o de; 1(c) dishgled o de. 2(a) Give me the book; 2(b) Give us the book; 2(c) Gizthebook. 3(a) a handbag; 3(b) a hambag. 4(a) Would you mind passing me that book? 4(b) Pass me that book. ANGGOTA KELOMPOK. SRI YUNIARTININGSIH (P2BA10009). YAYUK SUGIYARTI (P2BA10025). IHDA SYFAI (P2BA10010). Origins of Genetic Variation Among Offspring. The behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises in each generation. Peter van . Bodegom. Department of Systems Ecology. VU University Amsterdam. The Netherlands. Traits vary considerably within and between communities. Kattge. et al. 2011 GCB. Traits also tend to respond to climate manipulations.
