Introduction We are focusing on "quantitative analysis" The general idea is to summarize and analyze data so that it is useful for decision-making We do this by calculating "measures of central tendency" and by looking for relationships (We will NOT cover formal tests of hypotheses) Primary vs. secondary data sources Data on uses For example, tables or graphs are used to organize data, and descriptive values such as the average score are used to summarize data. Use a Statistical description of such a system. Methods of Collecting Data biomedical Signal processing ????????
