Question 1: Hindsight Bias

Answer:

The tendency to believe, after learning an outcome, that one would have foreseen it. (Also known as the "I-knew-it-all-along" phenomenon.)

Question 2: Placebo (Latin for "I shall please") Effect

Answer:

Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent.

Question 3: Informed Consent

Answer:

An ethical principle that research participants be told enough to enable them to choose whether they wish to participate.

Question 4: Correlation

Answer:

A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other.

Question 5: Independent Variable

Answer:

The experimental factor that is manipulated; the varible whose effect is being studied.

Question 6: Statistical Significance

Answer:

A statistical statement of how likely it is that an obtained result occurred by chance.

Question 7: Population

Answer:

All the cases in a group being studies, from which samples may be drawn. (Note: Except for national studies, this does not refer to a country's whole population.)

Question 8: Range

Answer:

The difference between the highest and lowest scores in a distribution.

Question 9: Case Study

Answer:

An obsercation technique in which one person is studies in depth in the hope of revealing universal principles.

Question 10: Scatterplot

Answer:

A graphed cluster of dots, each of which represents the values of two variables.The slope of the points suggests the direction of their relationship.The amount of scatter suggests the strength of the correlation (little scatter indicates highcorrelation).

Question 11: Random Assignment

Answer:

Assigning participants to experimental and control groups by chance, thus minimizing pre-existing differences between those assigned to the different groups.

Question 12: Confounding Variable

Answer:

A factor other than the independent variable that might produce an effect in an experiment.

Question 13: Replication

Answer:

Repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding extends to other participants and circumstances.

Question 14: Mode

Answer:

The most frequently occurring score(s) in a distribution.

Question 15: Mean

Answer:

The arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores.

Question 16: Culture

Answer:

The enduring behaviors, ideas, attitudes, and traditions shared by a group of people and transmitted from one generation to the next.

Question 17: Naturalistic Observation

Answer:

Observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation.

Question 18: Illusory Correlation

Answer:

The perception of a relationship where none exists.

Question 19: Debriefing

Answer:

The postexperimental explanation of a study, including its purpose and any deceptions, to its participants.

Question 20: Experiment

Answer:

A research method in which an investigator manipulates one of more factors (independent viarables) to observe the effect on some behavior or mental process. By random assignment of participants, the experimenter aims to control other relevant factors.

Question 21: Hypothesis

Answer:

A testable prediction, often implied by a theory.

Question 22: Theory

Answer:

An explanation using an integrated set of principles that organizes observations and predicts behaviors or events.

Question 23: Normal Curve (Normal Distribution)

Answer:

A symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean (68 percent fall within one standard deviation of it) and fewer and fewer near the extreme.

Question 24: Control Group

Answer:

In an experiment, the group that is NOT exposed to the treament; contrasts with the experimental group and serves as a comparison for evaluation the effect of the treatment.

Question 25: Double-blind Procedure

Answer:

An experimental procedure in which both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo. Commonly used in drug-evaluation studies.

Question 26: Random Sample

Answer:

A sample that fairly represents a population because each member has an equal chance of inclusion.
