In statistics, a histogram is a graphical representation, showing a visual impression of the distribution of data. It is an estimate of the probability distribution of a continuous variable and was first introduced by Karl Pearson. A histogram consists of tabular frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area equal to the frequency of the observations in the interval. The height of a rectangle is also equal to the frequency density of the interval, i.e., the frequency divided by the width of the interval. The total area of the histogram is equal to the number of data.

ReplyDeleteThis is a good attempt to talk discuss what's a histogram like.
Now, as you have seen more examples of histogram, you could probably expand your explanation on what you know about this kind of graphical representation (e.g. with different kinds of examples)
