Whilst the Null data set proved the highland as producing more Null observations. Another result showed that Mare/ Mare edges were types of topography that were more likely to produce TLPs by their average number of observations. Indicating that thorium rich areas are more likely to produce TLPs.

When comparing this to the Null observations >3ppm areas had 39.3 observations whilst areas of low thorium had 77.9 observations. It showed that TLP locations with amounts of thorium >3ppm had a higher average number of TLP observations 17.95 whilst the thorium deficient areas had 8.88. However, the geological survey (using Lunaserv Global Explorer) of a sample of 40 TLP locations and 40 Null locations demonstrated evidence for the outgassing theory. The results suggested no direct correlation with TLPs in respect of sunspots, Bow shock, Magnetotail and impact basin edges. Each area of investigation was compared to a dataset of mistaken TLP observations (The Nulls). Also, if they were close to impact basin edges. The investigation focused on whether the number of TLP locations was affected by sunspots, Bow shock, Magnetotail and detected radioactive thorium. electrostatic levitation and outgassing from radioactive sources or prove otherwise. The purpose was to correlate the data and provide evidence in support of the proposed theories e.g. The reported sightings of Transient Lunar Phenomena were statistically analysed using a dataset of observations from 1000 AD.
