The analysis is carried out by the hypothesis testing and the event tree method. The probability of detection for diversion of 8 kg Pu is found to be less than 95% if a large size granule consisting of small size particles gets sampled for measurements. To increase the probability of detection more than 95%, first, a new Material Balance Area (MBA) structure consisting of more number of Key Measurement Points (KMPs) is designed.

The independent variable in the experiment was the two different schemas used in the study (Geography student or tourist) and the dependent variable was the extent to which the participants could recall the story, specifically the number of words in this case. The results suggested that a change in schema of the same story would improve recall, as found by Anderson and Pichert.
