[QUOTE="Zyka, post: 544468, member: 17926"] think of it this way- if you go out to your favorite spot and take samples in one very small area and dont find any gold, that doesnt mean there is no gold anywhere else in that area. (good) scientific studies follow this same policy. sample different places and then compile the data to create an overall picture of the study. its impossible to sample every case the same way its impossible to check every square cm of dirt down to the bedrock in a whole area, so we have to used data projection to build a picture of our report, be that one for a mineralogical survey of an area or a report on the effectiveness of sonic repellent devices.
