3 Statistical Analysisdataanalysis Pptx This document provides a comprehensive introduction to statistics, including definitions, concepts, and methodologies used in statistical analysis. Introduction to statistics. measures of central tendency and dispersion. the phrase “descriptive statistics” is used generically in place of measures of central tendency and dispersion for inferential statistics. these statistics describe or summarize the qualities of data.

This document provides an introduction to statistics, including definitions, types, data measurement, and important terms. it defines statistics as the collection, analysis, interpretation, and presentation of numerical data. 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.
