Introduction to descriptive statistics - 1 hour

Data analysis tools can be grouped into several categories, each category aiming at answering a certain type of questions associated to a certain type of data. Descriptive statistics allow to summarize information contained in datasets using simple numbers such as the mean or the standard deviation; and charts such as box plots and scatter plots. This Webinar presents descriptive statistical features with applications using the XLSTAT statistical software.




  • A few definitions: descriptive statistics, variable, individual
  • Describing one qualitative variable: mode, flat sorting, pie charts
  • Describing the link between two qualitative variables: cross tabulation (contingency table)
  • Describing one quantitative variable: mean, standard deviation, median, quartiles, box plots
  • Describing the link between one quantitative variable & one qualitative variable: multiple box plots
  • Describing the link between two quantitative variables: scatter plot
  • 1 quantitative var. x 1 quantitative var. x 1 qualitative var.: scatter plot with colored points
