Abstrakt: Abstract: In many recent articles, medians have been used as a replacement of integral averages when the function fails to be locally integrable. A point x in a metric measure space (X,d,μ) is called a generalized Lebesgue point of a measurable function f if the medians of f over the balls B(x,r) converge to f(x) when r converges to 0. We know that almost every point of a measurable, almost everywhere finite function is a generalized Lebesgue point and the same is true for every point of a continuous function. We show that a function f\in M{s,p}(X),0
