2.6.1 Research Brief And Proposal Flashcards
(14 cards)
what was the sleep and stress study abstract about
- investigated changes in adolescents sleep from low to high stress
- study shows stressful times can have negative effects on adolescent sleep fragmentation
> especially with low chronic sleep reduction or high baseline stress
what is meant by a quasi experiment
A natural experiment is when a researcher does not deliberately manipulate the IV
> they take advantage of a naturally occurring IV ; participants are not randomly allocated to an experimental or control group/condition
- the DV of a natural experiment may be test in a lab, field or online setting
identify 2 strengths and 2 weakness of experimental design within your research
+ allows for control over variables
+ can establish cause and effect relationships
- may lack ecological validity
- results could be unreliable
identify 2 strengths and 2 weakness of the location (classroom) within your research
+ natural setting for students
+ accessible
- prone to distractions
- lack of control over extraneous variables
identify 1 strengths and 2 weaknesses of the sample within your research
+ can provide relevant data for the target population
- may not be representative
- sample size might be too small
identify 1 strength and 2 weakness of the sampling technique within your research
+ convenient
- potential bias
- may not be truly random
identify 1 strength and 1 weakness of the materials within your research
+ standardised materials > improves reliability
- might not fully replicate real life situations
identify 1 strength and 1 weakness of control within your research
+ helps reduce extraneous variables
- too much control may make it unrealistic
identify 1 strength and 1 weakness of validity within your research
+ can measure the intended variables effectively
- if it is too controlled then it may reduce external validity
identify 1 strength and 1 weakness of reliability within your research
+ can be replicated if properly controlled
- individual differences may affect consistency
identify 3 strength and 1 weakness of the ethics within your research
+ informed consent was given
+ debriefing was done
+ anonymity can be ensured
- possible psychological distress
what is the methodology used in your sleep quality investigation
- quasi experiment
- independent groups design
- IV = age of ptps
- DV = quality of sleep measured using PSQI
- 10 ptps under 25 (sixth form students)
- 10 ptps over 25 (sixth form teachers)
what is the procedure used in your sleep quality investigation
- downloaded and printed copies of PSQI
- 5 sixth form students were opportunity sampled from a cohort of 140 students
- 5 sixth form teachers opportunity sampled
- ptps were briefed on the experiment and asked if they consented to participating > once consent was gained, the experiment began
- in the classroom, ptps were given the PSQI and asked to fill out every question > time limit of 10 minutes
- at the end of the 10m, ptps were asked to hand in their responses
