09.Descriptive statistics:Measures of central tendency and dispersion (by hand using formulas)

These podcasts are for students interested in learning or reviewing topics in an introductory statistics class. Podcast topics include describing and summarizing data both graphically and numerically, probability, various distributions, confidence intervals, tests of significance, and exploration of bivariate data. 
This show focuses more on practice with using a graphing calculator and Microsoft Excel and less of the formulaic approach. 
Some of the podcasts are raw (unedited) clips from a live classroom. This course, taught on campus twice per week for 100 minutes, was recorded at the Lancaster Campus of Harrisburg Area Community College. 
This course requires the use of a graphing calculator such as a TI-83 or TI-84 and Excel.
