What is the definition of Scientific Method?
|
Making observations in a systematic way, following strict rules of evidence, and thinking critically.
|
|
Define hypothesis and Theories, then explain the differences between the two.
|
1. Hypothesis - A prediction made based on a theory.
2. Theory - Tentative explanations of facts and relationships in science. The differences are, A theory is an explanation yet to be proven. A Hypothesis is a prediction of the outcome of testing based on a theory. |
|
Explain and define a "Sample".
|
A Sample is a small group of participants that are studied in hopes of learning something that will apply to other humans or animals.
|
|
What is a representative sample and why is it important?
|
A representative sample means a sample must by typical to the rest of the population being studied. If the sample is not representative of the population being studied the study will NOT be valid.
|
|
What does Replication in research mean and why is it important.
|
Replication means to repeat a study to show it's accuracy and validity. The more a research project has been replicated the more trustworthy the results are considered.
|
|
What is the simplest of scientific inquiry and what is it's definition?
|
Descriptive Studies - Studying people as they live their lives and using observations to document their behaviors.
|
|
Define and describe the Survey Method of inquiry.
|
Survey Method - An approach that simply asks people questions about material or opinions. Advantage = you can get a lot of information quickly. Disadvantage = The accuracy of the information is in question, are people honest.
|
|
Define the Naturalistic Method.
|
Naturalistic Method - the careful observation and recording of information as it happens in a natural setting.
|
|
Define and Clinical Method of inquiry.
|
Clinical Method - The observation of people while they are in a clinical setting working with a mental health professional.
|
|
Define Correlational Method.
|
Correlational Method - Researchers measure two variables related in the study and see if they are statically related.
|
|
Define Variable.
|
Variable - a variable is anything in which its numerical value can be measured.
|
|
What are Quantitative measures?
|
Quantitative Measures - Are Numerical values can be assigned to each variable in the study.
|
|
What does the coefficient of correlation express?
|
It measures the strength of the correlation between two quantitative variables in statistical terms.
|
|
What is the range of the coefficient of correlation?
|
It can range from -1.00 and Zero to +1.00
|
|
What does it mean to be positively or negatively correlated?
|
A coefficient of +1.00 means it is positively correlated and the score on one variable should be the same on the other variable. -1.00 means it is negatively correlated and the scores on the two variables should not be the same or closely related.
|
|
Does correlational studies allow one to make a casual conclusion?
|
A correlation means two variables are related, but one cannot deduce that there is causation effect between the two variables.
|
|
What does a coefficient correlation of Zero denote or mean.
|
There is NO relationship between the two variables.
|
|
What is the most useful method of observation in reaching goals of understanding and influencing behavior...define this method.
|
Formal Experiments - This is designed to tell us about the relationships between 2 variables. It is carefully conducted experiments with controlled variables and can be used to determine cause-and-effect of behavior.
|
|
Define independent and dependent variables.
|
Independent Variables - arranged to allow for comparison of the participants under 2 or more conditions.
Dependent Variables - The measure of behavior that is contrasted in two or more conditions. |
|
which type of variable can be controlled or manipulated by the researcher?
|
The Independent Variable
|
|
Define Experimental and Control groups in an experiment.
|
Experimental Group - The group that receives the conditions of the Independent Variable.
Control Group - The group that does not receive any of the independent variable conditions. |
|
Define random assignment and why it is important.
|
Random Assignment - Participants must be assigned to groups randomly only, if other methods are used the experiment will be invalid.
|
|
What is Experimental Control?
|
Experimental Control - The researcher must insure that the independent variable is the only factor that has controlled the outcome, and that no other factors have influenced the outcome.
|
|
What is a Placebo?
|
Placebo - An inert or inactive condition without an experiment.
|
|
What is a Placebo Effect?
|
Placebo Effect - Changes in a behavior produced by a condition thought to be an inert or inactive, such as a Placebo Pill in medical experiments.
|
|
What is meant by a Blind Experiment?
|
Blind Experiment - Condition in which the researchers recording the data are not aware of which is the experimental and which is the controlled group.
|
|
What is Experimenter Bias?
|
Experimenter Bias - Condition in which the researchers are influenced in their evaluation of the data based on their beliefs of what the outcome should be.
|
|
What is Double Blind referring to?
|
Double Blind - A condition in which the neither the researchers nor the participants know who is in the controlled and who is in the experimental groups.
|
|
List and define at least 5 ethical principals in working with human participants.
|
1. Freedom from Coercion - should not coerce or pressure a person to participate.
2. Informed Consent - Participants must be informed thoroughly what they are getting involved with. 3. Limited Deception - Some experiments may need for the participants to be unaware of what it is for exactly, a) participants should be told everything they can be told to make a decision to participate, and b) they must be told immediately afterwards what the experiment was for. 4. Adequate Debriefing - Participants deserve to know the results afterwards. 5. Confidentiality - Researchers are obliged to keep information learned about participants private. |
|
Define the 3 ethical principles in working with animal participants.
|
1. Necessity - Experiments with animals should be conducted only if the information to be gained is necessary to learn about human and animal behavior.
2. Health - All animal subjects should be cared for in a manner to insure good health. 3. Humane Treatment - Every effort must be made to insure the comfort of the animals in the experiment. |
