In the given scenario, when a bar on a bar graph ends in between two lines, it indicates that the exact numerical value of the bar cannot be precisely determined based on the graph alone. However, there are still a couple of options to consider in this situation:
1. The numerical value of the bar:
- a. cannot be determined: This option is correct because the bar ending between two lines does not provide a clear, specific value, making it impossible to determine the exact numerical value from the graph alone.
- b. should be rounded up to the nearest line: This option is incorrect because rounding up to the nearest line would be an assumption and not a precise calculation based on the graph.
- c. can be estimated: This option is a plausible approach in this case. Even though the exact value cannot be determined, an estimation based on the position of the bar relative to the lines can provide a rough idea of the value.
In conclusion, when a bar on a bar graph ends in between two lines, the most accurate choice is that the numerical value of the bar cannot be determined solely from the graph, but it can be estimated based on its position.
