LEARNING OUTCOMES At the end of this module, you will be able to: produce and interpret frequency distribution tables; produce and interpret graphs ***********************************************************  FREQUENCY DISTRIBUTION: Data can be presented in various forms depending on the type of data collected. A frequency distribution is a table showing how often each value (or set of values) of the variable in question occurs in a data set. A frequency table is used to summarize categorical or numerical data. Frequencies are also presented as relative frequencies, that is, the percentage of the total number in the sample. EXAMPLE : Frequency distribution of peptic ulcer according to site of ulcer Site of ulcer Frequency Percent Gastric ulcer 24 30.0 Duodenal ulcer 50 62.5 Gastric and duodenal ulcer 6 7.5 TOTAL 80 100 GRAPHICAL METHODS: Frequency distributions and are usually illustrated graphically by plotting various type...

Instructions What is covered by this tutorial? This introductory course is intended to provide a practical introduction to working with the program Matlab ® by The MathWorks , particularly focussing on aspects being relevant for data processing in psychological research . Matlab is often used in experiments applying psychophysical methods such as electro-encephalography (EEG), eye tracking, or registration of galvanic skin response (GSR). Put more generally, Matlab is very useful for the evaluation of large data sets that are often acquired automatically, as it is the case in logfile analysis or internet experiments as well. Why Matlab? Matlab is a programming language often used in psychological research. It is especially suitable for data analysis but can be applied for prog...

Topic :Research Methodology The process used to collect information and data for the purpose of making business decisions. The methodology may include publication research, interviews, surveys and other research techniques, and could include both present and historical information. The research methodology enabled the team to organize their efforts into one cohesive and conceptual product idea generation task for us Definition The methods section describes the rationale for the application of specific procedures or techniques used to identify, select, and analyze information applied to understanding the research problem, thereby, allowing the reader to critically evaluate a study’s overall validity and reliability. The methodology section of a research paper answers two main questions: How was the data collected or generated? And, how was it analyzed? The writing should be direct and precise and always written in the past tense. Importance of a Good Methodology Section You must explain...
