Answer:

the researcher is measuring the deviation in the results

Explanation:

The deviation of a statistical result shows how far results depart from the center of the measurement. In other words, the results show how the measurements depart from the mean or average value. By taking the measurement values, the upper limit can be established. Next, the lower limit of the results can be measured. Next, the standard deviation can be measured to determine the nearness of furtherness of the values from the control values. Then, a plot of the standard deviation against the results can be plotted.

Once it crossed state lines it conflicted with federal law, specifically the Article 1 Section 8 of the constitution that Congress had exclusive national power over interstate commerce.
