contents We investigate possible quantifications of Banach-Saks sets and weak Banach-Saks sets of higher orders and their relations to other quantities. We prove a quantitative version of the characterization of weak $ξ$-Banach-Saks sets using $\ell_1^{ξ+1}$-spreading models and a quantitative version of the relation of $ξ$-Banach-Saks sets, weak $ξ$-Banach-Saks sets, norm compactness and weak compactness. We further introduce a new measure of weak compactness. Finally, we provide some examples showing the limitations of these quantifications.
