Ch 2 case study Flashcards
After analyzing their data, what would researchers do next?
present their findings
After formulating hypotheses and predictions, what step must a psychologist take next?
Test the hypotheses and predictions through empirical research.
A test of intelligence is given to a subject. The subject scores a 110 on the first administration. Six months later, the same subject is given the test again and receives a score of 75. After another six months have passed, the subject is given the test one last time and receives a score of 138. What conclusions can be drawn from these scores?
The scores are not reliable.
A theory is
a broad idea that can be used to explain observations.
Descriptive Research :
1-observation
2-surveys and interviews
3-case studies
Experimental Research :
1-independent and dependent variables
2-Quasi-experimental design
What is the term for an educated guess based on a theory that can be tested?
hypothesis
In the field of psychology, descriptive research serves the purpose of observing and recording ______ that can be used as data.
behavior
In order to test a hypothesis and conduct valid empirical research, a psychologist first needs
a concrete way to measure the variable of interest.
After researchers have gathered data, what do they do next?
1-Researchers would analyze their data to see if it supports the predictions of their hypothesis.
2-Researchers would analyze the findings to see what the results say about the theory used to guide their study.
Correlational research involves studies that are concerned with identifying the relationships between two or more___________in order to describe how they change together.
variables
Results are considered reliable if they can be
replicated.
An experiment
involves manipulating one or more variables in order to determine their effect on other variables.
The third step in the scientific method is the need to collect and analyze data, that is, the testing of hypotheses by conducting empirical
research :
Research
The entire group about which a researcher wants to draw conclusions is called the
population.
The key feature of a correlational study is :
that the factors of interest are examined to see how changes in one relate to changes in another.
__________ research takes place in a controlled setting and provides researchers a way to control many aspects of the situation and exclude potential confounds.
laboratory
Researchers must use_________ methods to determine whether causal relationships exist between variables.
Experimental
A researcher is interested in studying visibility of tattoos on perceptions of competence for work. What type of design would be appropriate for this topic?
case study
observation
___________ research methods include observation, surveys and interviews, and case studies.
Descriptive
The entire group about which the investigator wants to draw conclusions is the _________
population
Statistics are used to ________________ the data collected from a research study.
report
What setting would a researcher choose if they needed to remove many of the complex factors of the real world to conduct their research?
laboratory
The distance between the highest and the lowest scores in any data set is considered the:
range
