The other half received a version in which there was no eye contact. Data were collected on success ratings. (a) Is this study experimental, observational, or mixed? Why? (b) Identify all factors, factor levels, and factor-level combinations. There are 2 factors (male, female) each with 2 factor levels (eye contact, no eye contact) for a total of 4 factor level combinations (c) What is the basic unit of study?
