Department of Statistics Overview of the Course Professor Name : Nabil A. Ibrahim Professor title at MSA: Professor of Biostatistics & Calculus International consultant in genetic improvement Prof. of Limnology & Genetics - (CLAR) LECTURE OUTLINE Course contents & breakdown Be familiar with statistics as a tool Be familiar with different types of gaining information from of statistics different types of data for making right decisions. LECTURE ILOs A1: Define fundamentals of biostatistics; C2: Demonstrate statistical reasoning and as in systematic collection, organization, contextually. interpreting and statistical analysis of experimental data consequently making predictions & proper decisions based on the experimental data. Course contents: Types of Data & Types of Statistics. Population versus sample and their types. Central tendency measures & the relationship between Mean, Median, and Mode. Measures of dispersion for ungrouped and grouped data. The concept of the analysis of variance (ANOVA). ------------------------------------------------------Mid term ----------------------------------------------------- The calculations of the analysis of variance (ANOVA). The concept of probability. Adding and multiplying probabilities. The normal and standard normal distributions. Application of normal and standard normal distributions in the field of biology. Correlation & regression with its application on biological data. Statistics The word "statistics" refers to a range of techniques and procedures for collecting, analyzing, interpreting, displaying data, and making predictions & decisions based on data. Statistics is the science of gaining information from numerical and categorical data. It’s safe to say that, nowadays statistics is used in every field of science. Biostatistics Biostatistics is the branch of statistics responsible for translating the scientific data into meaningful information that can then be used to make logical and beneficial decisions in biology, public health, health policy, clinical medicine, health economics, genomics, proteomics, and a number of other disciplines.  Types of Statistics – Descriptive Statistics ▪ Consists of methods for organizing, displaying, and describing data with help of tables, bar charts, pie charts, graphs, …etc. and summary results. – Inferential Statistics ▪ Consists of methods that use sample results to help make decisions or predictions about a population. Descriptive and inferential statistics are interrelated. It is almost always necessary to use methods of descriptive statistics to organize and summarize the information obtained from a sample before methods of inferential statistics can be used to make more thorough analysis of the subject under investigation. References: Kathleen F.
