Question 1: Illusory Correlation

Answer:

Perception of a relationship where there is none.

Question 2: central Tendency

Answer:

A single number or value that describes the typical or central score among a set of scores. Refers to how to measure the center of a set of data.

Question 3: Normal Curve

Answer:

A symmetrical, bell-shaped curve. 2%(>/< 30sd), 95% (30sd), 68%(15sd)

Question 4: Theory

Answer:

Explanation using an integrated set of principles that organizes observations and predicts future occurrences.

Question 5: Mean

Answer:

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

Question 6: Experiment

Answer:

a research method involving an investigator who manipulates one or more factors (independent variables) to observe the effect on dependent variables.

Question 7: Descriptive Methods

Answer:

Describes behaviors; case studies, surveys, naturalistic observations

Question 8: Correlation Coefficient

Answer:

e.g. +0.70 ; The sign shows the direction (positive or negative) the number indicates the strength. The closer to 1, the stronger the correlation.

Question 9: Pie chart

Answer:

Graphic display of data in which frequencies or percentages are represented as "slices" of pie.

Question 10: Placebo Effect

Answer:

Experimental results caused by expectations alone. A phenomenon in which a fake treatment (placebo) improves a patient's condition because the person has the expectation that it will be helpful

Question 11: Frequency Polygon

Answer:

A graphic display of a frequency distribution in which the frequency of each score is plotted on the vertical axis, with the plotted points connected by straight lines

Question 12: Experimental Group

Answer:

the treatment group in an experiment. One variable is tested at a time. Given a version of the independent variable

Question 13: Mode

Answer:

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

Question 14: Overconfidence

Answer:

Tendency to believe we know more than we do; inhibits critical thinking

Question 15: Control Group

Answer:

receives a placebo to serve as a contrast from the experimental group

Question 16: Variability

Answer:

The amount of about dispersion of scores some central value.

Question 17: Operational Definition

Answer:

A carefully worded statement of the exact procedures (operations) used in a research study - specification of how a researcher measures a research variable and forces researchers to discuss abstract concepts in concrete forms.

Question 18: Empirical Approach

Answer:

Basing conclusions on observable evidence. Researchers collect info that may justify a cause-effect conclusion; curious, skeptical, humble

Question 19: Population

Answer:

all those in a group being studied from which samples may be drawn

Question 20: Random Sample

Answer:

a sample that fairly represents a population. Each member has an equal chance/probability of inclusion.And unbiased representation of a group

Question 21: Correlational Methods

Answer:

Relates different factors or variables (anything that contributes to a result); it cannot tell us anything about cause and effect, only whether or not they are related

Question 22: Sampling Bias

Answer:

an unrepresentative sample (e.g. only asking people are a dance class if they enjoy dance)

Question 23: Debriefing

Answer:

Post-experimental explanation of a study. Incls. purpose and participant deception

Question 24: Naturalistic Observation

Answer:

observing behaviour in natural situations w/o trying to manipulate and control the situation; people behave differently when they know they're being watched

Question 25: Double-Blind Procedure

Answer:

both researcher + participants are ignorant about whether participants have received treatment or placebo to prevent research bias due to demand characteristics or placebo effect

Question 26: Dependent Variable

Answer:

the outcome factor; the variable that may change in response to manipulations of the independent variable. -- A variable that is assumed to depend on, or be caused by one or more other variable; effect or outcome in a cause effect relationship.
