Question

An experiment was performed where radish seedlings were grown in red, blue, green, and white light. The height of plants was measured once per week for 8 weeks. If you were making a graph, plant height goes on which axis: x or y? EXPLAIN!

Answer 1

In the experiment, plant height is the dependent variable and it should be plotted on the y-axis (vertical axis) of a graph, while the type of light, an independent variable, should be on the x-axis (horizontal axis).

Step-by-step explanation:

In an experiment where radish seedlings are grown in different colors of light and their height is measured, the height of the plants would be the dependent variable because it depends on the color of light which is the independent variable. This information should be reflected correctly on a graph to accurately represent the data collected.

On a graph, the independent variable is traditionally placed on the x-axis, which is the horizontal axis. In the context of your experiment, the color of light is the independent variable because it's the condition you are controlling. The y-axis, which is the vertical axis, typically represents the dependent variable, which in your case is the height of the plants as they are dependent on the color of light they are exposed to.

Therefore, for the experiment in question, the height of the plants should go on the y-axis. This setup allows anyone who is looking at the graph to easily see how the height of the radish seedlings changes in response to the different colors of light they are exposed to.
