Angular correlations in four-jet events from hadronic decays of the Z have been compared with second-order matrix element calculations. Such comparisons can be used to determine an apparent fraction of four-quark events contained in the data. We find R_4q, the overall ratio of the experimentally measured apparent fraction of four-quark events to the theoretical prediction to be in agreement with previous analyses, but with larger systematic errors. Differences in shape between the correlations of the data and the second-order theory have been observed as a function of m_34, the invariant mass formed by the system of the two least energetic jets. These differences, expressed by the value of R_4q, exhibit a shallow maximum in the region of 20 GeV and become negative at higher values of m_34. Some of these features can also be qualitatively observed in models which include higher order effects such as a combination of matrix elements with a parton shower.
