A meta-analysis is a survey in which the results of the studies included in the review are statistically similar and are combined and analyzed as if they were one study.
Meta-Analysis is a statistical technique for combining the findings from independent studies.
Meta-Analysis is most often used to access the clinical effectiveness of healthcare interventions

Meta-Analysis of trials provide a Precise estimate of treatment effect.
The validity of the meta-analysis depends on the quality of the systematic review on which it is based.
Good meta-analyses aim for complete coverage of all relevant studies, look for the presence of heterogeneity, and explore the robustness of the main findings using sensitivity analysis.

Explain what Cohen's d and r 2 measure when calculated for a t test

MathJax(?): Can't find handler for document MathJax(?): Can't find handler for document Let P = ( 1 2 , 1 2 ) and Q = ( 1 2 , 1 2 ) be two vertices of a regular polygon having 12 sides such that PQ is a diameter of the circle circumscribing the polygon. Which of the following points is not a vertex of this polygon?
(A) ( 3 1 2 2 , 3 + 1 2 2 )
(B) ( 3 + 1 2 2 , 3 1 2 2 )
(C) ( 3 + 1 2 2 , 1 3 2 2 )
(D) ( 1 2 , 3 2 )
If P and Q are the end points of the diameter, it is quite clear that the equation of the circle must be
x 2 + y 2 = 1
Therefore, all the vertices must lie on this circle. Now, checking from the options, we find that every point given in the options satisfies the above equation. Now I am stuck.
How else should I tackle the sum?

When can a meta-analysis combine the data from all studies into one hypothesis test?

1. This can be done for any meta-analysis
2. This can only be done when similar methods were used to sample the same population.
3. This can only be done when computing confidence intervals not hypothesis tests.
4. This can be done when similar methods were used to sample different population.

i'm seeking out thoughts for a 15-hour mathematical enrichment course in a chinese language high faculty. What (pretty) simple concern would you advocate as a subject for any such course?
historical past/issues:
My students are generally pretty good at math, but many of them have no longer been uncovered to rigorous or summary mathematical reasoning. an amazing topic would be one that could not be impossibly hard for students who have by no means written or study proofs in English.
i have taught this magnificence three times earlier than. (a part of the purpose that i'm posting that is that i have used up all my thoughts!) the primary semester I taught an introductory range theory elegance (which meandered its way toward a proof of quadratic reciprocity, though I think this become in the end too advanced/abstract for some of the students). the second one semester I taught fundamental graph idea and packages (with a focal point on planarity and coloring). The 1/3 semester I taught a class at the Rubik's dice.
the students' math backgrounds are pretty numerous: a number of them take part in contest math competitions, and so are familiar with IMO-fashion techniques, however many aren't. a number of them may additionally realize some calculus, however I cannot assume it. all of them are superb at what in the united states is on occasion termed "pre-calculus": trigonometry, conic sections, systems of linear equations (though, shockingly, no matrices), and the like. They realize what a binomial coefficient is.
So, any ideas? preferably, i'd like to find some thing a bit "sexy" (like the Rubik's cube) -- tries to encourage wide variety theory through cryptography seemed to fall on deaf ears, however being capable of "see" institution idea on the cube became pretty popular.
(Responses specifically welcome from folks who grew up in the percent -- any mathematical subjects you desire were protected within the excessive college curriculum?)
