Exam 11: Validity of Research Results in Quantitative, Qualitative, and Mixed Research

In conducting her literature review, Carol noticed that most of the articles she was finding were 25 years old and she used them to develop her study. As a result her study's temporal validity may be affected.

When a significant amount of time passes between the first and second treatment so that one or more things could be at least partially responsible for a change seen in the research participants, it could be an example of regression artifacts.

One way to promote theoretical validity in qualitative research is to:

Pattern matching refers to:

Internal validity refers to the degree to which a researcher can accurately claim that a causal relationship exists between two variables and that the observed strength of the relationship is accurate.

A researcher places a video camera in a classroom to tape lessons that are part of one of the treatment conditions. The video camera is likely to increase the probability of:

If the qualitative and quantitative parts of a mixed study have used different sets and numbers of research participants and you have made appropriate generalizations when you combine the data from these sets of research participants, you have achieved:

Identify and explain the types of validity or legitimation used in mixed research.

Describe three of the strategies a qualitative researcher can use to ensure the research validity of her study.

Dr. Sanjay is studying whether his racism awareness program increases his research participants' awareness of issues of race and ethnicity in his city. On Monday, he gives an attitude survey to his participants to gauge their awareness. On Tuesday through Thursday, he puts them through his program. On Wednesday, a local predominantly black church is firebombed and the KKK claims responsibility. On Friday, Dr. Sanjay gives his awareness survey again and finds awareness of racial issues has increased dramatically. This example illustrates the possibility of ______________ as a plausible rival explanation.

Jason's study looked at the reactions of members of the two major political parties to the person who was elected as president. It is possible that his study had selection-maturation validity threats.

Anna is writing up her qualitative research study. She took in depth notes on what took place with the participants as well as what she saw and heard when working with the participants. She did this to improve the study's:

When the researcher can draw clear causal conclusions from what went on in a study, this is called:

Sarah is conducting an ethnographic study of fifth grade classes using an interdisciplinary curriculum. After she collects her data, she goes back and asks each teacher to help her out by checking the accuracy of the descriptions she has written of the classrooms. This technique is called:

If the way a variable is measured changes during the course of a study, this threat to validity is called:

Which of the following does not represent a threat to internal validity?

When the participants in the different treatment conditions have different characteristics that vary along with the independent variable, this is called:

Theoretical validity refers to:

If a researcher has successfully quantitized qualitative data and qualitized quantitative data, he/she has achieved:

Reactivity can influence:
