Introduction to exploratory 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. Exploratory statistics allow to summarize information contained in datasets of various volumes using dimension-reduction and segmentation features. This Webinar presents popular exploratory statistical features with applications using the XLSTAT statistical software.


Basic knowledge in descriptive statistics (mean, median, scatter plots...)


  • A few definitions: exploratory statistics, data mining, variable, individual
  • Reminder: describing two quantitative variables using a scatter plot
  • Expanding description on multivariate dataexploration and segmentation
  • Reducing dimensions with Principal Component Analysis (PCA)
  • Data segmentation with Agglomerative Hierarchical Clustering (AHC)
