"The science of pure mathematics, in its modern developments, may claim to be the most original creation of the human spirit." -- (Alfred North Whitehead, 1861-1947))

Eratosthenes (276-194 B.C.): This Greek mathematician calculated the circumference of the earth with an error of less than 2%. The computational process and reasoning used by Eratosthenes involved simple geometric reasoning that is taught in modern secondary school geometry classes.

Assignment 5

Reading: Chapter Review (pages 51-53).
On page 59, look at the use of box plots as presented in Figure 1.15. Be able to "read" these plots. Note that these are not modified box plots. That is, they don't use the "show the outliers" technique. (Which of the plots clearly have outliers?)

Exercises 1.52. 1.53. In each exercise. put the data into a calculator list and get all of the statistics produced by 1-Var Stats. Also, use your calculator to produce box plots and histograms for the data. Sketch these neatly on your homework paper. Write a few intelligent statements relating to your observations.


Items for reflection:

You are in a summary section for Chapter 1(Sections 1.1 and 1.2).

Make sure you get a good grasp on the concepts ofstandard deviation and variance. The section summary for Section 1.2highlights these and other important concepts.

Shape of data is important: ALWAYS PLOT YOUR DATA.

For distributions that are roughly symmetric:Mean and standard deviation are useful indices.
For distributions that are skewed, mean and standard deviationare less useful. The five-number summary presents a better overallpicture.
