Question

Draw a subdivided bar graph to illustrate the given data:

Years	Wheat	Barley	Oats
1991	34	18	27
1992	43	14	24
1993	43	16	27
1994	45	13	34

Answer 1

Hint: First of all, we will draw the required axis, on which on the x – axis side, we will keep the years and on the y – axis side, we will draw the numbers as required quantities.

Complete step by step solution:
Let us first of all look at the given table:-

Years	Wheat	Barley	Oats
1991	34	18	27
1992	43	14	24
1993	43	16	27
1994	45	13	34

We can see that we have the data of 4 years that are 1991, 1992, 1993 and 1994 with us which we are required to represent in the bar graph form.
So, we will take the normal co – ordinate axis, on which we will keep the years towards the x – axis side and the quantities on the y – axis side. Let us represent this in some figure as given below:-

Now, we have assigned the years and the quantities.
Also, if you notice the small coloured boxes in the graph denote the colour how that data will be represented by.
Now, we will put in the values of Wheat to make it much clear and then add on others one by one as well.
Let us add the wheat quantities in the above given graph. We will then obtain:-

Now, similarly like this, we will add in the values of barley on the top of wheat.
Then, we will obtain the following graph:-

Now, similarly like this, we will add in the values of oats on the top of barley.
Then, we will obtain the following graph:-

Thus, we have the required graph.

Note: The students must note that they might make the mistake of not writing the values inside like we did in the graph but writing the values gives us a better and clear picture to then evaluate the data.
The students must also know that the bar graph is an easy way to represent and look at the data without giving much of an effort.
