In this master's thesis the problem of determining the uncertainty for an estimator of an unknown parameter is considered. The case we study is the estimation of gravity using a reversible pendulum. This involves the estimation of the point where two regression lines intersect. The estimated gravity is a function the coordinates of this point. One way to determine the uncertainty of this estimator is to use bootstrap methods. In this paper three different bootstrap methods are considered. To compare these three methods, the bias and the standard deviation of the methods are evaluated. The results show that all three methods are quite satisfying but one method is a little better than the others.
