Question 1

Systematic review

Answer 1

• integrates research evidence from multiple sources
  -cochrane collaboration
  quant- meta anlaysis
  qual- meta synthesis

Question 2

Meta-analysis

Answer 2

Uses findings from each study in a systemic review to calculate effect size

Question 3

effetc size

Answer 3

determines if independent variable led to outcome

can determine th relationship between variables across multiple studies

Question 4

Advatages of meta- anlysis

Answer 4

• are objective and supportive by statistical anlaysis
• the power is increased
• The research ? needs to be near identical and enough strong studies to merit its use

Question 5

Steps in Meta-anlaysis

Answer 5

willl look simlar rto research process

• quesiton will be narrow or focused
• design will sample primary studies that are adress the narrow ro focus research question
• Lit search: risk for publication bias
• Evaluations of study quality: varying approcah must be doen by ultiple researchers to agree on all ratings of quality.

Question 6

EAch study

Answer 6

• date location, atttition, particpant characteristics, follow up, effect size

Question 7

Calculation of effects

Answer 7

• Cohen’s D: qunat data with scale type numerical results
• Odd’s ratio: used where outcomes are tacotomies
• Pearson’s R: is used for non experimental studies

Question 8

Data anlysis

Answer 8

Forest plot: can determin if a meta nalysis is appropriate to use based on the effect size

Question 9

Steps in a metasynthesis

Answer 9

• not a lit review
  Problem: not narrow focused
  Design multiple researchers
  -may look outside published peer review journals
• dissertations
• describe what studies they include or exclude
  lit review less involved
