This video focuses on effective ways to understand and organize data using descriptive statistics. Analyzing data collected from studies of young music students, the video helps viewers sort through basic data-interpretation concepts: measures of central tendency, levels of measurement, measures of dispersion, and graphs. A wide range of organization principles are covered, including mode, median, and mean; discrete and continuous data; nominal, ordinal, interval, and ratio data; standard deviation; and normal distribution. Animation and graphics clarify and reinforce each concept.
