Exam 16: Interpreting Research and Practical Projects
It is risky to interpret data without knowing exactly what they _______.
B
How is generality different from the reliability of effects?
Asking about the generality of our interpretations addresses the question: "If experimental findings are used under circumstances that are somewhat different, will the same kind of effects be obtained?" This question is similar to the question raised by curiosity about the reliability of a study's outcomes, but it is not the same. Reliability asks: "If experimental procedures are repeated, will the same effects be obtained?" We make this same distinction in discussing replication in chapter 10. In both instances we are making predictions, but the basis for these predictions is different. Concluding that a study's effects are reliable predicts that the same results would be obtained if the procedures were repeated more or less exactly. Concluding that our interpretations are general predicts that the same kind of results would be obtained even if certain features of the study were somewhat different.
Describe the primary concern regarding the independent variable when interpreting a study.
The primary concern is that the independent variable and other features of the intervention condition in which it is embedded were implemented as designed and that they were consistent from session to session. For research conducted in highly controlled settings such as laboratories, this fidelity and consistency is usually assured. Researchers using applied settings, on the other hand, often struggle to make sure that the procedures in both control and treatment conditions are implemented as intended. It is often the case, for instance, that these procedures require varied personnel to comply with specific protocols.
Why can focusing too much on the experimental question sometimes be a detrimental influence on interpretations?
Identifying a study's outcomes is only appropriate if the project's procedures and data are:
Why is it important to assess, one at a time, each of the components of measurement?
What are the consequences of drawing conclusions that are not justified by the experiment's procedures and data?
______ addresses the question of if experimental procedures are repeated, will the same effects be obtained. While ______ addresses the question of "if experimental findings are used under different circumstances, will the same kind of effects be obtained?"
The amount of time, effort, and money that a researcher has invested can often lead to what form of research?
Researchers are interested in each of the following generalities, except:
All things considered, a study is either good enough to warrant conclusions or it is _________.
The task is not just to interpret the data, but to interpret:
When someone interprets a study or project, he translates the language of _____ into the language of the culture.
______ has to do with the meaningfulness of experimental interpretations under circumstances that are different from those that generated the data.
Describe how differences of opinion regarding study interpretations are an important part of the scientific process.
If a study is well designed and conducted, the variability between phases ideally represents the effects of ___________.
Why are extraneous variables problematic for a study and an investigator's interpretations of it.
The primary challenge in interpreting a project is deciding how each of its ______ might have affected data.
Explain the following statement: "the task is not just to interpret the data, but to interpret the entire experiment."
When evaluating a study, an investigator must be satisfied about the ______ of data.
