Essential Statistics for Bioscientists. Mohammed Meah

examples of common statistical tests.

      4 Does not describe areas such as enzyme and substrate reactions (e.g. Scatchard plots), or non-linear curve fitting or multiple regression.

      5 Helps in deciding the factors to consider for study designs.

      6 Helps in choosing appropriate tests to analyse data and to display data.

      The reader should be able to answer the following questions from the use of this book.

       What:

       Is your study design?

       Sample size is appropriate?

       Are the descriptive statistics appropriate for the sample data?

       Is the difference between standard deviation and standard error of the mean?

       Is a confidence interval?

       Is a normal distribution?

       Is significance and how do you test for it?

       Is the interquartile range?

       Is the difference between parametric and non-parametric tests?

       How do you:

       Graphically describe your data?

       Plot a frequency distribution plot?

       Check if the sample data is normally distributed?

       Decide on which statistical test to use?

       Do a paired (related groups) t test?

       Do an unpaired (independent groups) t test?

       Do a non-parametric test (Wilcoxon)?

       Do a non-parametric test (Mann–Whitney)?

       Do a 1-way ANOVA test?

       Do a repeated measures 1-way ANOVA?

       Do a 2-way ANOVA test?

       Do a correlation test?

       Use Microsoft Excel software to do statistical analysis?

       Use SPSS software to do statistical analysis?

       Use Prism software to do statistical analysis?

      I hope the readers and users of this book will (a) get a better understanding of statistical concepts and (b) be able to use the software packages with more confidence and thereby aid them in their degree studies.
