ous variables with a lot of possible values. For the latter, it divides the range of possible values into “bins” (equally sized ranges of values). The count of observations in each bin is then plotted as the height of a bar, and the width of the bar reflects the range (in the case of discrete values, the range is defined by the midpoints between these values. A histogram is useful to depict the distribution of values of a variable. The size of the bins is important though, as it determines how smooth or
