Pharmacology has historically been an interdisciplinary field, positioned at the point of convergence of physiology, biochemistry, organic chemistry, behavioral science, and medicine. Ann Emerg Med 1990;19:153-8. 2PowerPoint Presentation: In experimental pharmacology we have to understand when to use and how to calculate and interpret different measures of central tendency (mean, median and mode) and dispersion (range, IR and standard deviation) We have to identify the types of error encountered in statistical analysis, the role of sample size and implications for decision making. Genetics studies, since its beginning, used statistical concepts to understand observed experimental results. The M.Sc. Some genetics scientists even contributed with statistical advances with the development of methods and tools.

The null hypothesis is defined as the theory that no difference exists between study groups. 12PowerPoint Presentation: If the change can be either in direction, µ A is not equal to µ B, a two tailed and one tailed tests are carried out. No sharp delineation exists between the two, but bioinformatics tends to deal with data in many dimensions, so-called “big data,” such as in genomics. The IR is defined as the difference between the lower quartile and upper quartile. If a study were to compare two means, the null hypothesis (H o )=µ A =µ B Probability deals with the relative likelyhood that a certain event will occur or will not occur. 8Measures of Dispersion: Measures of Dispersion Range Interquartile range Standard deviation The range is defined as the difference between the highest and lowest values.

Randomization is the random process of assigning treatments to the experimental units. Biostatistics are the development and application of statistical methods to a wide range of topics in biology. If we added one more value, the median would be calculated by taking the two middle numbers and dividing by two. For example, if number of treatment = 3 (say, A, B, and C) and replication = r = 4, then the number of elements = t * r = 3 * 4 = 12 = n. The pharmacology of this century will bring together an even wider range of disciplines, combining traditional aspects of pharmacology with novel approaches drawn from other disciplines, such as biophysics, biomedical engineering, and molecular genetics. 32References: References Guyatt G, jaeschke R, Heddle N, Cook D, Shannon H, Walter S, Hypothesis testing. 13Statistical Tests: Statistical Tests Student’s t-Test (paired or independent) Wilcoxon Mann-Whitney rank sum test Wilcoxon signed rank test Contingency tables (Chi-square tests) 14Student’s t-Test : Student’s t-Test Two types Independent Paired X and Y are the two populations.
