Stem plots: A stem plot is a visual representation of a distribution where each data point is split into a 'stem' (leading digits) and 'leaf' (trailing digit). It helps to display the shape and spread of data.
Range: The range represents the difference between the maximum and minimum values in a dataset. It gives an indication of how spread out the data points are.
Histograms: Histograms are graphical representations that divide data into intervals called bins, showing the frequency or count of observations within each bin. They provide a visual representation of distributions similar to bar graphs but for continuous data.
