Which is the best type of graph to show the number of markers in each classroom, if markers come in boxes of 20?
Pictograph
To show the number of markers in each classroom when markers come in boxes of 20, the most suitable type of graph would be a bar graph. Here's why:
1. Collect the data: Start by collecting the number of markers in each classroom. For example, Classroom A has 35 markers, Classroom B has 60 markers, Classroom C has 25 markers, etc.
2. Determine the units: Since each box of markers contains 20 markers, divide the total number of markers in each classroom by 20 to determine the number of boxes. For example, Classroom A would be 35 markers / 20 = 1.75 boxes.
3. Create a bar graph: On the x-axis, label each classroom (e.g., Classroom A, Classroom B, Classroom C, etc.). On the y-axis, represent the number of boxes of markers. For each classroom, draw a bar with a height proportional to the number of boxes required to represent the total count of markers.
4. Include a key/legend: Add a key or legend to clarify that each bar represents a certain number of boxes and provide the corresponding marker count.
By using a bar graph, you can clearly represent the number of markers in each classroom, accounting for the fact that markers come in boxes of 20.
