ABSTRACT

The previous chapters have covered statistical theory, generating random numbers, frequency distributions, data display in stem and leaf plots, population characteristics, measures of central tendency and dispersion, sample size effects, Tchebysheff theorem, and the normal bell-shaped curve. These chapters laid the foundation for understanding statistical concepts using S-PLUS. Basically, a random sample of data from a population can be graphically displayed and described by measures of central tendency and dispersion. This chapter, and the others that follow, describe the role probability plays in statistics. Basically, probability operates under seven fundamental rules that are covered in Chapters 11-16.
