If you are conducting several trials using different variables, you will need to summarize the nature in the changes in each trial. An example may very well be : some sort of. I purchased five different types of batteries, 8 each. n. I randomly assigned matched pairs of two electrical power into four sets, for 20 total trials. c. I developed a standard technique of using the camera to help consistently model the demands of everyday camera employ. d. I ran each group of batteries through this test, recording the time taken for the camera to shut off from depleted batteries. orite. I calculated the mean time of each one manufacturers batteries. f. I calculated may be batteries required to supply one years usage of the camera. g. I multiplied the cost of the batteries by the number of batteries to calulate your expected annual cost for each manufacturer.
7. Identification with the variables and the equipment. Many experiments are improved by using a control. The normal variability of data in your control can give you a preliminary understanding of the "noise level" inherent inside your data. It also provides a baseline along which to measure the trials deviation, so you can assess the importance of your specifics.
8. Undoubtedly identified data. You should construct tables to hold the data from your samples. In most cases, you ought to have your variables (Xs) together with outcome (Ys) clealy listed so you can visually and mathematically show any correlation.
9. Discussion of your measurement system and its reliability and repeatability. This can be a key to Six Sigma quality. Every project has a review of the measurement system. Many experiments are affected more through the noise in the data than the actual variables. This is a common omission among discipline fair projects. Discuss and understand the causes of variability in your end result, including things such as experiment order, time of day, ambient temperature, difference in batches or samples, and experimenter variability : viewing angle, insufficient perfection on measurement tools, or anything else. It will show that judges that you understand there are other things that can but will affect your data.
10. Analysis of the data as it relates to your hypothesis. Once you have the data, you should try to visually graph the data and see if you have correlations or calculations which support your hypothesis. One important things to note is that if your experiment disproves or fails to prove your hypothesis, do not think you have failed! It is very crucial for you to let the Scientific Method work, and let you learn by what your experiment did not tell you. You can get superb scores on projects that fail to validate your hypothesis for those who have a well designed together with thorough experiment.
11. Conclusions in the experiment. Did people prove your hypothesis? Whether you did or not necessarily, make sure it is clear whether you proved or do not prove your hypothesis.
