(BQ) Part 2 book "Biostatistics" has contents: Estimation theory, hypothesis testing, further statistical tests for the distribution and parameters of random variables, further tests on correlation, statistical tables. | Part II Biostatistics 87 Introduction Probability theory and mathematical statistics are in a specific relation, which is rather difficult to circumscribe. No doubt that the questions and problems of statistics can mostly be traced back to problems of the applications of probability theory. Moreover, biostatistics or biometry, ., the biological application of mathematical statistics, is itself a huge and complicated branch of the statistical science. The questions to be discussed in the sequel are well-known not only in biological statistics, but also in the general statistical practice, and so the knowledge of these consitutes part of the general intelligence in natural science. According to this, the material of this part of the book just slightly differs from a statistical book intended for students participating in an elementary course of mathematics. The specification for biostatistics and biometry is only reflected in the material of the examples. Otherwise, we have been trying to maintain a good balance between the theoretical part and the practical details and exercises. Regarding the latter ones, it would have been useful to include statistical software packages, too. However, the limits of this book did not allow this. Similarly to the accepted common style of statistical books, at some places we only give a recipe-like description of the statistical procedures. We did not include a very lengthy list of references, however, we can refer to the great opportunities that the various internet browsers provide. The nature of the subject is well characterized by the expressions ”sufficiently”, ”mostly”, ”usually”, ”generally” etc. that the Reader will come across frequently in this part of the book. In purely mathematical texts such expressions would rarely have place. We provide some statistical tables, necessary in many cases for the solution of the exercises, although these tables are already easily available on the internet, too. Solving the exercises .
