exhibited by both groups. Which research design does this exemplify?
a) Descriptive research ✅
b) Experimental research
c) Case study research
d) Cross-cultural research
Rationale: Descriptive research involves observing and recording behaviors without
manipulating variables, used to describe patterns and trends in populations.
QUESTION 2: Which research method examines one individual or a small group in depth to
understand complex developmental phenomena?
a) Descriptive research
b) Case study research ✅
c) Experimental research
d) Longitudinal research
,Rationale: Case studies allow detailed analysis of unique or complex developmental cases.
QUESTION 3: A study tracking the same children from age 5 to 15 to observe changes in social
skills is an example of:
a) Cross-sectional research
b) Longitudinal research ✅
c) Descriptive research
d) Correlational research
Rationale: Longitudinal research examines developmental changes over time in the same
subjects.
QUESTION 4: Observing playground interactions among children from different cultural
backgrounds is an example of:
a) Descriptive research
b) Cross-cultural research ✅
c) Experimental research
d) Case study research
Rationale: Cross-cultural research studies behavior and development across diverse cultural

manipulating hours of sleep is an example of:
a) Descriptive research
b) Experimental research ✅
c) Case study research
d) Longitudinal research
