We did this lab in which we used 3 brands of hand sanitizers and did the kirby bauer test. We measured the zone of inhibition for each of the three trials in millimeter. I need to make a graph, probably a line graph but im not sure what to put for the x and the y axis because we have three trials with three hand sanitizers.

To create a graph for your lab results, you need to determine the appropriate values for the x and y axes. In this case, you can consider the following approach:

1. X-axis: Typically, the x-axis represents the independent variable, or the variable you intentionally manipulate or control. In your case, you could use the different hand sanitizers as your independent variable. Since you mentioned having three trials with three hand sanitizers, you can label the x-axis with the three brands of hand sanitizers you tested.

2. Y-axis: The y-axis generally represents the dependent variable, or the variable that is measured or observed as a result of changing the independent variable. In your experiment, you measured the zone of inhibition for each of the three trials. Therefore, you can label the y-axis as "Zone of Inhibition (mm)."

Once you have determined the labels for your x and y axes, you can proceed to plot the data points on a line graph. Each data point will represent the measurement for a particular hand sanitizer in a specific trial. You can connect these data points with a line to visualize any trends or patterns in the results.

Remember to appropriately annotate the graph with a title and axis labels to make it clear and understandable.
