What is the scientific method and how is it applied to psychological
research? Correct AnswerThe scientific method is the set of
assumptions, rules, and procedures scientists use to conduct research. In
addition to requiring that science is verifiable, the scientific method
demands that procedures are free of personal bias.
What is the definition of a hypothesis? Correct Answer- A specific and
falsifiable prediction about the relationship between two or more
variables.
What is an operational definition? Provide an example. Correct Answer-
An operational definition refers to a precise statement of how a
conceptual variable ( abstract idea that form the basis of research
hypotheses ) which is turned into a measured variable ( varialbes
consisting of numbers that represent the conceptual variables )
(Conceptual Variable) Depression - (operational definition) Number of
negative words used in a creative story; number of appointments made
with a psychotherapist
,Why are ethical guidelines needed within psychological research?
Correct Answer- These are needed with psychological research is the
prevent physical and/or emotional harm to the participants.
What are the various research methods in the field of psychology?
Correct Answer- Descriptive Research
Correlational Research
Experimental Research
What do psychologists study? Correct Answer- • Biological
Foundations
• Mental Life
• Change
• Self and Others
• Potential and Dysfunction
What is descriptive research? Correct Answer- research designed to
provide a snapshot of the current state of affairs.
,What is Correlational Research Correct Answer- research designed to
discover relationships among variables and to allow the prediction of
future events from present knowledge.
What is Experimental Research Correct Answer- research in which there
is a random assignment of research participants into two groups. This is
followed by a manipulation of a given experience for one group while
the other is not manipulated. One group is the experimental group that
receives the manipulation. The other group is the control group that
does not. The two groups are then compared to determine the influence
of the manipulation.
Independent Variable Correct Answer- The variable in an experiment
that is manipulated or compared
Dependent Variable Correct Answer- The variable in an experiment that
is measured; the outcome of an experiment
Control Group Correct Answer- The group of subjects in an experiment
that does not receive the independent variable
, Experimental Group Correct Answer- EXPERIMENTAL GROUP is the
group receiving the independent variable
What does a correlational research design examine? Provide an
example. Correct Answerresearch designed to discover relationships
among variables and to allow the prediction of future events from
present knowledge.
Describe examples of a positive and a negative correlation. Correct
Answer- Correlational-To assess the relationships between and among
two or more variables.
Postiive - As children age they get better at math
Negative - Age of a child and the number of diapers they use "Negative
correlation, the variables move in inverse, or opposite, directions. As
one variable increases, the other variable decreases. For example, there
is a negative correlation between self-esteem and depression. Positive
correlation is when there is an increase in one variable it is associated
with an increase in another variable. For example: with height and
weight, taller people tend to be heavier."
What are the differences in interpretations of correlational and
experimental designs? Correct Answer- In correlational studies a
researcher looks for associations among naturally occurring variables,
