BRAIN STORY CERTIFICATION FINAL
PAPER PRACTICE QUESTIONS WITH
VERIFIED ANSWERS PACKAGE
●● Operational Definition
Answer: Clear, precise definition of your variables that allows
replication and collection of reliable data.
●● Qualitative Data
Answer: Descriptive data, such as eye color.
●● Quantitative Data
Answer: Numerical data, ideal and necessary for statistics.
●● Population
Answer: Everyone the research could apply to.
●● Sample
Answer: The people or person specifically chosen for your study.
●● Correlation
Answer: Identifies the relationship between two variables.
,●● Positive Correlation
Answer: Variables increase and decrease together.
●● Negative Correlation
Answer: As one variable increases, the other decreases.
●● Independent Variable
Answer: Purposefully altered by the researcher to look for effect.
●● Dependent Variable
Answer: Measured variable that is dependent on the independent
variable.
●● Placebo Effect
Answer: Any observed effect on behavior caused by the placebo.
●● Double-Blind
Answer: Experiment where neither participant nor experimenter is aware
of condition assignments.
●● Single-Blind
Answer: Only the participant is blind to the condition.

Answer: Assigning participants to control or experimental groups at
random.
●● Naturalistic Observation
Answer: Observing people in their natural settings.
●● Case Study
Answer: Studies one person in great detail.
●● Meta-Analysis
Answer: Combines multiple studies to increase sample size and examine
effect sizes.
●● Mean
Answer: Average, used in normal distribution.
●● Median
Answer: Middle number, used in skewed distribution.
●● Mode
Answer: The number that occurs most often.
, ●● Standard Deviation
Answer: Average amount the scores are spread from the mean.
●● Statistical Significance
Answer: Results not due to chance; experimental manipulation caused
the difference in means.
●● Effect Size
Answer: Data has practical significance; magnitude of impact.
●● Percentile Rank
Answer: Percentage of scores in a distribution that are less than a given
score.
