I have some questions about Carbon Dating. My questions are inline:-
First of all, I would like to know that is there such a thing as a Median Date when it comes to calibrating the date range?
Secondly, I would like to know that are the later dates more reliable for paleography analysis?
Thirdly, I want to know that what is the importance of 1 Sigma and 2 Sigma variances in carbon dating? Is it possible to calibrate our dates without them?
1). A median date is based on several dates from a given feature. This is because trees being long lived may have a very broad date range as would its charcoal. In such cases it is the most recent date that is preferred but a median is provided as the older potential date.
2). An older date could be used but a midian date may make more sense.
3). Since carbon 14 in the atmosphere varies year over year the calibration can be a bit fuzzy the older the sample. Thus understanding the full scope of the potential age range could be important. Thus 1st, 2nd and 3rd sigma may play an important part.
