  2. Histograms in Excel • Since this is not obvious from the menus or help, the following may be of use • Install the Analysis Tool Pack Add-in (Tools/Add-ins/Analysis ToolPack) • This depends on which options you originally installed with Excel • Then use Tools/Data Analysis/Histogram • You can only get help on histograms from the Histogram pop-up window • See the Oakland sample file for an illustration of the use of ”bins” & chart output

  3. General Concerns • Reliability • Repeated measures of the same condition are reasonably similar • Validity • Statistic measures what it purports to measure • (worries about systematic error & bias)

  4. Specific SPSS Topics Covered • Descriptive statistics • Frequencies • Histograms • Cross-tabulations • Value labels • Recoding & transforming data • Missing data or observations • Other stuff: Scatterplots
