Summability is a branch of mathematical analysis in which an innite series which is usually divergent can converge to a finite sum s (say) by ordinary summation techniques and become summable with the help of dierent summation means or methods. C method was given by Ernesto Cesåro such that ordinary Cesåro summation was written as ( C, l) summation whereas generalised Cesåro summation was given as (C, α). In 1913, Hardy  proved a theorem on (C, a), a > 0 summability of the series. In this paper, comparison of relative strength of absolute summabilities for functions has been investigated on different sets of parameters.
