Question

Managers at all levels of an organisation need adequate information to perform their respective tasks. One study investigated the effect the source has on the dissemination of information. In this particular study the sources of information were a superior, a peer and a subordinate. In each case, a measure of dissemination was obtained, with higher values indicating greater dissemination of information. To verify whether the source of information significantly affects dissemination, you perform the ANOVA test. The following table partially report the results: Source of Variation SS Df MS F p−value F crit Between groups Within groups 2.077 ? ? ? ? 2.716 ? ? ?
