Document Summary
In this experiment, 32p source was used to detect the electrons emitted from the source. The diluted source was pipetted same amount into three different plates to test for consistency of pipetting technique. The new set of data were given by the instructor to perform the statistical data analysis of nuclear decay counts measured. The two series value with one having small counts and the other having larger counts. the chi-square test were measured from the probability of expected and observed. The beta decay is the three-body decay, which emits electrons in matter. These energetic electrons are weaker and more difficult to detect than in alpha decay1. Therefore, the amplifier in a scintillator must be required. The statistical data helps the problem of measuring nuclear phenomena1. Even when the experiment performance is perfect to eliminate determinant error, there is always a random error due to the statistical nature of radioactive decay1.
