You are interested in understanding how a manager's leadership style impacts the performance of a work group. You are trying to decide the best way to design a research study to examine this relationship and want to try to maximize both internal and external validity as well as control over extraneous variables.
To what extent does the type of research design used impact the extent of internal and external validity? What research design might you choose to study this topic?
Why is there a need for control of extraneous variables when conducting research, and why is it important?
Let's say you think the leader's gender might be an extraneous variable in this study. Discuss three techniques you might use to control this variable and how those techniques would be used in this study.
Is control always possible or desirable? What conclusions can we draw about a study that lacks control?© BrainMass Inc. brainmass.com September 18, 2018, 2:07 pm ad1c9bdddf
When experiments are conducted in research design, the main goal is usually to provide a demonstration of the cause and effect relationships which exists between the dependent and the independent variables. This is usually done in a manner that will enable statements to be drawn about people at large. The wellness of drawing statements about people at large is referred to as a study's generalizability. A study with a high external validity has the capability of readily allowing its findings to be generalized to the population at large. On the other hand, a study which allows its findings to the generalized to the population at large while ensuring that the confounding variables are clearly eliminated within the study is referred to ...
