What is radiometric dating and how is it used

An additional nice feature of isochron ages is that an "uncertainty" in the age is automatically computed from the fit of the data to a line.

A routine statistical operation on the set of data yields both a slope of the best-fit line (an age) and a variance in the slope (an uncertainty in the age).

Whether there's a data point on the Y-axis or not, the Y-intercept of the line doesn't change as the slope of the isochron line does (as shown in Figure 5).

(This topic will be discussed in much more detail below.) Where the simple methods will produce an incorrect age, isochron methods will generally indicate the unsuitability of the object for dating.

Since the data points have the same Y-value and a range of X-values, they initially fall on a horizontal line: half-lives will include zero within its range of uncertainty.

(The range of uncertainty varies, and may be as much as an order of magnitude different from the approximate value above.

(For brevity's sake, hereafter I will refer to the parent isotope as ).

In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.

(Rocks which include several different minerals are excellent for this.) Each group of measurements is plotted as a data point on a graph.
