From an absolute value of 0 to 1.
What does a negative “r” indicate in a correlational design?
An inverse relationship between two variables.
What is an experimental design?
A controlled test of a hypothesis where the researcher manipulates one variable to discover its effect on another.
What is the best way to prove the existence of a cause-effect relationship?
Experimental design.
Name one way to improve experimental trials.
Have a control group.
Name another way to improve experimental trials.
Employ random assignment.
What is a trial called when random assignment is used?
Randomized controlled trial (RCT).
What is a placebo control used for in experiments?
To improve experimental trials by simulating the treatment without actual effects.
What is the key feature of a single-blind experiment?
Participants do not know which group they are in.
What is the key feature of a double-blind experiment?
Neither the participants nor the researchers know which group the participants are in.
What is a quasi-experimental study?
research method that examines cause-and-effect relationships without random assignment

Name 3 types of effect that can influence results in developmental studies.
Age, time of measurment and cohort effects.
What is the purpose of designing developmental studies carefully?
To understand what is influencing the results.
What do cross-sectional studies measure?
A trait across a number of age groups or categories at the same time.
Name 2 vulnerabilities of cross-sectional studies.
Cohort effects and selective survival.
Give an example of a cross-sectional study measurement?
Hours of exercise per week among different age groups.
What do longitudinal studies measure?
The same variable(s) in the same individuals at different ages.
What is selective attrition in longitudinal studies?
When participants who drop out are not representative of the original sample.
What is terminal decline?
The gradual loss of cognitive abilities as individuals approach death.
What is a practice effect in longitudinal studies?
Improved performance on tests due to familiarity with the test rather than actual change.
What is one limitation of cross-sectional studies compared to longitudinal studies?
They reflect age differences rather than changes.
What challenge arises with participant selection in cross-sectional studies?
Selective survival of more able participants.
What is an issue with age ranges in cross-sectional studies?
Deciding on appropriate age ranges and how to divide the sample.
What is a challenge when comparing measures across age groups?
Finding comparable measures for older and younger adults.
What do sequential studies combine?
Cross-sectional and longitudinal designs.
Name one key feature of sequential studies.
Enrolling a group of people at different ages and following them over time.
Name one advantage of sequential studies.
They allow the study of change over time.

Sample
______ refers to how trustworthy the results are over time.
Reliability
An example of reliability is ______ reliability, which checks if results are stable over time.
Test-retest.
______ refers to whether a questionnaire measures what it proposes to measure.
Validity
