Week ½ Exam 1:
Week 3 Exam 2:
1.)Identify the independent variable in a quantitative study studying the effects of a GRE preparation course on GRE scores for Black and Latino male and female students.
2.)Identify the dependent variable in a quantitative study studying the effects of a GRE preparation course on GRE scores for Black and Latino male and female students.
3.)Which suggestion is a useful tip when designing a visual literature map?
4.) Which variables does the experimenter intentionally use in order to more clearly isolate the relationship between the independent and dependent variables?
5.)A mediating variable transmits the effects between an independent and dependent variable.
Week 4 Exam 3:
1.)How is theory used in quantitative research?
2.)A student wants to examine the role of education in history by looking at required curriculum across different college campuses. Additionally, the student will interview faculty in history departments for their perspective of the curriculum. The student hopes to identify areas of improvement for history departments in higher education. Is this human subjects research?
3.)A priori theoretical perspectives can be used in both qualitative and quantitative studies.
4.)Which theoretical perspective would be most appropriate for studying faculty perceptions on
Success between Black and White students?
5.)Which of the following best describes grounded theory?
Week 5 Exam 4:
2.)Which word implies a quantitative approach in a purpose statement?
3.) A purpose Statement appears at the end of the introduction.
4.)The deficiencies model of writing an introduction is based on identifying the research problem first.
5.)Of the following, which one is not the purpose of reviewing studies in an introduction?
6.)You should only include “recent literature” in a literature review.
Week 6 Exam 5:
Publicly traded firms will have higher growth rates than privately held firms. | Alternative Directional | |
---|---|---|
There is no difference in growth rates between publicly traded firms and privately held firms. | Null Hypothesis | |
Growth rates will vary between publicly traded firms and privately held firms. | Alternative non-directional |
Western societies have seen an increase in violence and antisocial behavior in schools
and communities (Pollack, 1998). Juvenile crime rates have increased four times since
the early 1970s (Cook & Laub, 1997). After the shock of the Columbine school
massacre in the United States and other violent incidents, communities are demanding
interventions to help prevent similar occurrences.
(Cook & Laub, 1997)
Constructivism- Theory in education which states individuals do not passively acquire knowledge, rather they construct new knowledge and understandings through experience and social disclosure, integrating new information with what they already know (prior knowledge).
Post-positivism- the perspective that theories, hypotheses, background knowledge, and values of the researcher can influence what is observed. (therefore, post-positivists pursue objectivity by recognizing the possible effects of biases)
Human subjects research- a systematic, scientific investigation that can be either interventional or observation and involves human beings as research subjects, commonly known as test subjects.( therefore interviews are considered human subjects research but surveys are not considered human subjects research)
Independent Variable- A variable that stands alone and isn't changed by the other variables you are trying to measure.
Dependent Variable- The variable that depends on the other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variables or variables
Predictor- The variable That researchers believe has some sort of association with an outcome variable. (ex. Sense of belonging predicts school climate)
Outcome- The result of the action of one more independent variable. It can also be defined as any outcome variable associated with some measure, such a survey. (ex. Academic Achievement is the outcome of a reading intervention)
Alternative Directional hypothesis- Specifies the direction of the tested relationship (ex. Increases or decreases), stating that one variable is predicted to be larger or smaller than null, value but not both.
Null hypothesis- the hypothesis that there is no significant difference between specific populations, any observed difference being due to sampling or experimental error.
Alternative non-directional hypothesis- states that there is a difference between the mean scores of two groups but does not specify which group is expected to be larger or smaller. (ex. Hypothesis states a variable influences another variable, but does not say whether it is an increase or decrease or if the influences is positive or negative)
Research approach- the procedure selected by the researcher to collect, analyze, and interpret data. There are three approaches to result: quantitative, qualitative, and mixed methods.
World view- the perspective of the researcher which influences their research methodology (ex. Post-positivism, constructivism, etc.)
Research design- refers to the overall strategy utilized to carry out research that defines a succinct and logical plan to tackle established research questions through the collection, interpretation, analysis, and discussion of data. (Ex. Experimental design, non-experimental design)
Meditating variables- the variable that intervenes (mediates) the relationship between the independent and dependent variables. For example, in a study on socioeconomic status and reading ability in children, parental education background could be a mediating variable.
