Deep-inelastic ep scattering data, taken with the H1 detector at HERA, are used to study the event shape variables thrust, jet broadening, jet mass, C parameter and two kinds of differential two-jet rate. The data cover a large range of the four-momentum transfer Q, which is considered to be the relevant energy scale, between 7 GeV and 100 GeV. The Q dependences of the mean values are compared with second order calculations of perturbative QCD applying power law corrections proportional to \(1/Q^p\) to account for hadronization effects. The concept of power corrections is investigated by fitting simultaneously a non-perturbative parameter \(\overline{\alpha}_{p-1}\) and the strong coupling constant \(\alpha_s\).
