Exploring Grouped Frequency Distribution Tables: The difference between FDTs 

This brief video is part 1 of 7 in a series about summarizing and visualizing quantitative data using GFDTs and histograms. In this video, we demonstrate the key difference between FDTs and GFDTs. The means by which the data is grouped and the frequencies aggregated is visually demonstrated. The manner in which the shape of the distribution can be explored using FDTs and GFDTs is discussed. In addition, we also explore an alternative definition of the mode which uses GFDTs.
