The History of statistics can be said to start around 1749 although‚ over time‚ there have been changes to the interpretation of the word statistics. In early times‚ the meaning was restricted to information about states. This was later extended to include all collections of information of all types‚ and later still it was extended to include the analysis and interpretation of such data. In modern terms‚ "statistics" means both sets of collected information‚ as in national accounts and temperature

Math 143 – ANOVA Analysis of Variance (ANOVA) 1 Recall‚ when we wanted to compare two population means‚ we used the 2-sample t procedures . Now let’s expand this to compare k ≥ 3 population means. As with the t-test‚ we can graphically get an idea of what is going on by looking at side-by-side boxplots. (See Example 12.3‚ p. 748‚ along with Figure 12.3‚ p. 749.) 1 Basic ANOVA concepts 1.1 The Setting Generally‚ we are considering a quantitative response variable as it relates to one or

(Hint: annualized variance is equal to 12*monthly variance. Also‚ please do not report variances and covariances in %‚ which would not make sense.) 2.

Introduction Biogeochemical cycles are important to the sustainability of all life. Chemical elements necessary for the growth and reproduction of all organisms have a limited quantity on earth at any one time‚ other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms
