Answer to question# 1)
In meta-analysis all the results of scientific studies related to one topic are combined, and re-analysed
It helps us reach the weighted average outcome and it also tells us how each study may contrast , thus help us generate hidden patterns and relations.
When all the information related to one specific topic is collected and analyzed totgether, the results are bound to be more significant.
Thus the correct answer choice is : B: Meta-analysis is reviewing all the literature
.
Answer to question# 2)
We analyze all the available sources of data, and researches just to draw a conclusive final conclusion about the research question.
Thus the correct answer choice is D
.
Answer to question# 3)
The effect size varies from 0 to 1, 0 implies the effect is too weak, an effect size of 1 implies the effect is too strong and an effect size of 0.5 would imply that the effect is medium
Hence the correct answer choice I B
.
Answer to question# 4)
The effect size is a measure that tells us about the significance of the treatment. It is unit free and helps compare multiple studies, for which the results are otherwise incomparable. Thus it serves as a standardized tool of comparing different researches.
Thus the correct answer choice is: E: both A and B are true
