Problem Overview:
The task is to create a bar graph based on the data provided in the table. The data shows the number of volunteers each day for a project over five days (Monday to Friday). The goal is to:
1. Write a title for the graph.
2. Label the axes appropriately.
3. Choose an appropriate scale for the y-axis.
4. Draw the bar graph.
Step-by-Step Solution:
#### 1.
Title the Graph
The title should clearly describe what the graph represents. Based on the data, a suitable title could be:
-
"Number of Volunteers Each Day for a Project"
#### 2.
Label the Axes
-
X-axis (Horizontal Axis): This axis will represent the days of the week. Label it as "Day."
-
Y-axis (Vertical Axis): This axis will represent the number of volunteers. Label it as "Number of Volunteers."
#### 3.
Choose an Appropriate Scale for the Y-axis
The data ranges from 12 to 27 volunteers. To accommodate this range and ensure clarity, we can choose the following scale:
- Start the y-axis at 0.
- Use intervals of 5 (e.g., 0, 5, 10, 15, 20, 25, 30).
- This scale ensures that all values fit comfortably within the graph and are easy to read.
#### 4.
Draw the Bar Graph
Using the chosen scale and labels, draw vertical bars for each day corresponding to the number of volunteers. Here’s how the graph would look:
-
Monday: 12 volunteers
-
Tuesday: 18 volunteers
-
Wednesday: 15 volunteers
-
Thursday: 24 volunteers
-
Friday: 27 volunteers
Each bar should reach the height corresponding to the number of volunteers for that day.
#### Final Graph Layout:
-
Title: Number of Volunteers Each Day for a Project
-
X-axis: Days of the week (Monday, Tuesday, Wednesday, Thursday, Friday)
-
Y-axis: Number of Volunteers (scale: 0 to 30 with intervals of 5)
Explanation:
-
Title: Clearly identifies the purpose of the graph.
-
Axes Labels: Ensure that the reader understands what each axis represents.
-
Scale: A well-chosen scale makes the graph easy to read and interpret. In this case, using intervals of 5 ensures that all data points are visible and the differences between them are clear.
-
Bars: Each bar visually represents the number of volunteers for a specific day, making it easy to compare the data across days.
Final Answer:
\[
\boxed{\text{Number of Volunteers Each Day for a Project}}
\]
This is the title of the graph. The rest of the solution involves labeling the axes, choosing the scale, and drawing the bars, as explained above.
