Question

The runs scored by two teams $A$and $B$in first $10$ overs are given below:

$\begin{array}{ccccccccccc}\text{Overs}& I& II& III& IV& V& VI& VII& VIII& IX& X\\ \text{Team}A& 2& 1& 8& 9& 4& 5& 6& 10& 6& 2\\ \text{Team}B& 5& 6& 2& 10& 5& 6& 3& 4& 8& 10\end{array}$

Draw a line graph depicting the data, making the graphs on the same axes in each case in two different ways as a line graph and as a bar chart.

Answer 1

Here, over is an independent variable and run is a dependent variable.

So, we take overs on $x$-axis and runs on $y$-axis.
Let us choose the following scale:
On $x$-axis: $1cm=1$ over
On $y$-axis: $1cm=1$ run
Now, let us plot $(I,2),(II,1),(III,8),...,(X,2)$ for team $A$ ,

$(I,5),(II,6),(III,8),....(X,10)$ for team $B$.

These points are joined to get the graph representing the given information as shown in the figure below.​

In order to visually represent the data using the bar graph, we need to follow the steps given below.

Step 1:

Draw the horizontal axis and vertical axis.

Step 2:

label the horizontal axis. (Overs)

Step 3:

Write the names on the horizontal axis, such as $I,II,III,IV,V,VI,VII,VIII,IX,X$.

Step 4:

Now, label the vertical axis. (Runs)

Step 6:

Finalize the scale range for the given data. ($1cm=1$ run

Step 7:

Observe the plot points:

For $A$ : $(I,2),(II,1),(III,8),...,(X,2)$

For $B$: $(I,5),(II,6),(III,8),....(X,10)$

Finally, draw the double bar graph that should represent each category of the pet with their respective numbers.
