Interpreting Communication Research by Frey, Botan, Friedman, & Kreps Chapter 3 Field Experimental Research

Introduction to Field Experiments A field experiment is an experiment conducted in a natural setting Field experiments are usually not full experiments, i.e., they are quasi- or pre-experiments

Field Experiments Two issues determine the type of field experiment (1) whether the independent variable can be manupulated (see p. 56) (2) whether one experimental group or multiple groups are studied (see p. 57) In addition, randomization of subjects to groups is usually not possible in field experiments

TAKE A FEW MINUTES TO WRITE DOWN What do we lose in an experiment without manipulation of the independent variable? without multiple conditions (groups)? without randomization of Ss to conditions?

A Difference between quasi- and pre-experiments Quasi-experiments use pretests, measurements of Ss prior to collecting data Pre-experiments do not use pretests to assess whether the groups start off equivalent

Examine Krep’s “A Field Experimental Test and Revaluation of Weick’s Model of Organizing” (1) Briefly summarize the study. (2) Critique the study, pointing to its strengths and weaknesses.
