SOURCES OF ERROR




Every experiment tries to prove its hypothesis as best as it can; however, many problems may occur that can alter the experiment in a negative way. Many problems may occur that can change the results causing the experiment to be not exactly correct. In testing the cuttings, problems may have occurred within the plants that could not have been determined. The plants from which the cuttings were taken may have been diseased or sick. This would affect the experiment in a major way due to the affect that it would have on the growth patterns.
The plant hormones could have also been applied in an ill way. Too much of to little may have been applied to the cuttings. Too much may have caused the cuttings to be overwhelmed by the chemicals that the hormones contain.
After the cuttings were placed in the soil, errors may have occurred due to the amount of water that was fed to the plants. The cuttings may have been over watered of under watered.
The grow light and heat pad that were placed in with the cuttings may have been a source of error. The light and the pad may have produced too much heat that may have caused the cuttings to wilt.
Finally, the measurements of the cuttings may not have been exact. The soil may have been uneven and the ruler may not have allowed for exact answers.
