External and internal validity
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?
