Also, more trials and independent data tests could be performed to increase the significance and reliability of the data. Instead of 5, 10 trials would create a greater number of data sets and the accuracy of the experiment. More independent variable data tests could be performed at smaller intervals (10 lux, 20 lux, 30 lux, 40 lux, 50 lux, 60 lux, 70 lux) would also increase the accuracy.
