Exam 2: Quantitative, Qualitative, and Mixed Research

Which type of research is more likely to be exploratory?

A variable that varies in type or kind is called a(n):

A researcher does a study of a curriculum on mass transit. She assigns a group of students from a rural school to receive the curriculum. She assigns a school in a major urban area to the comparison condition. She measures the results of a posttest on the curriculum. She finds that the groups score the same on the posttest. What can you conclude from this study?

The variable that is presumed to cause changes in another variable is called a(n):

The correlation between test scores and grades is:

The views about research that are held by a group of researchers and included assumptions, concepts, values, and practices are known as research paradigm.

The form of qualitative research that focuses on understanding people's experiences through the use of stories is:

What kind of research is the deductive or confirmatory scientific method most closely associated with?

A researcher carries out a study examining the effects of a new reading program on reading achievement as measured by a standardized test. He chooses two first-grade classes to carry out the study. After the study is done, he finds that group who received the new reading program performed better than the control group. He also discovers, however, that the group he chose to receive the new program had better prior reading performance. An extraneous variable in this study is:

Which type of research relies more on non-numerical data (e.g., words and images)?

The variable that is presumed to be influenced by one or more independent variables is called a(n):

A researcher carries out a study examining the effects of a new science program on scores on a standardized science test. He chooses two seventh-grade classes to carry out the study. After the study is done, he finds that group who received the new program performed better than the control group. He also discovers, however, that the group he chose to receive the new program had better prior science achievement. In this study, the prior science achievement is:

What kind of research would is most closely associated with "studying the culture of an educational context?"

Describe the characteristics of experimental research that make it more advantageous for drawing causal conclusions

By combining two or more research methods in a mixed methods research study, you increase the strength of your study because you make it less likely you will miss something or make a mistake.

A researcher studies achievement by children in poorly funded elementary schools. She develops a model that posits parent involvement as an important variable. She believes that parent involvement has an impact on children by increasing their motivation to do school work. Thus, in her model, greater parent involvement leads to higher student motivation, which in turn creates higher student achievement. Student motivation is what kind of variable in this study?

Grounded theory research focuses on further testing of a theory after the researcher has completed preliminary experiments.

Which of the following is an example of nonexperimental research?

A mixed method study is one that uses:

A variable that delineates how a relationship of interest changes under different conditions or circumstances is which of the following?
