The sample size of your experiment would be:
the number of spices + the types of controls you used
the total number of disks you placed per plate
the total number of disks in your entire experiment
the number of replicates of each treatment you did
the number of different spices you used
In reporting the results of your experiment (assuming some of your disks have zones of inhibition), what data will be graphed?
the average zone size in mm for each type of treatment and control
the average zone sizes for each plate
the number of zones of inhibition per plate
the treatment zone size minus the control zone size for each treatment type
the sum of the zone sizes in mm for every treatment replicate and plate
In the experiment comparing the antibacterial effectiveness of spices on bacteria, what result do you expect for the negative controls you used?
a moderate size clear zone where bacterial growth was inhibited around the circumference of the - control disk
bacterial growth right up to the edge of the - control disk (no inhibition)
a large clear zone where bacterial growth was inhibited around the circumference of the - control disk
a clear zone of inhibition around the circumference of the - control disk with a few small colonies growing in it
In the experiment comparing the antibacterial effectiveness of spices on bacteria, what result do you expect for the positive controls you used?
bacterial growth right up to the edge of the - control disk (no inhibition)
All of the above
a clear zone where bacterial growth was inhibited around the circumference of the + control disk
no bacterial at all will grow on the plate
In preparing a figure of your results (assuming you get zones of inhibition to report), you will plot the _________ on the x axis, and the _______ on the y axis.
