bajantara,

i've worked with statistics for many years. the fact that it is randomized is a good thing. experiments such as the one i described are designed for randomized events. that is why just one persons observations are not sufficient, but many people in our community need to do the experiment, post their results here, and then we can evaluate the results. we need approximately 30 people to do this experiment for the results to be meaningful with a p<0.05

If you do not understand p<0.05, don't feel bad. Most laypeople do not understand it. Here is a short explanation about significance, p-value, null hypothesis testing, etc:
