The count of various animals in a farm is given below. Draw the bar graph for the data. Animals Ducks Sheep Hens Rabbits Number 20 4 12 16

We know, A bar graph is a pictorial representation of numerical data in the form of rectangles (or bars) of uniform width and varying heights. The height of a bar represents the frequency of the corresponding observation. x - axis represents the observation and y - axis represents the frequency. Given, Animals Ducks Sheep Hens Rabbits Number 20 4 12 16 Therefore, we get:
