Which unit of measurement would be appropriate for the dependent variable?
Which unit of measurement would be appropriate for the dependent variable?
milliliters
kilograms

The graph for this data would be a bar graph.
The graph for this data would be a bar graph.
True
False
False. The appropriate graph for this data would be a line graph, as it would show the continuous relationship between the independent variable (water temperature) and the dependent variable (dissolve time). A bar graph is used to compare discrete categories or groups.
The graph for this data would be a bar graph.
The graph for this data would be a bar graph.
True
False
False. The appropriate graph for this data would still be a line graph, as it would show the continuous relationship between the independent variable (water temperature) and the dependent variable (dissolve time). A bar graph is not suitable for representing this relationship.
