Histogram

Any histogram is known to be an accurate representation of the distribution of numerical data. Being an estimate of the probability distribution of a continuous variable, the histogram was first introduced by Karl Pearson as a kind of a bar graph. To make a histogram, you need to divide the range of values into a series of intervals and then to count how many of the values fall into each of the intervals.
