standard deviation (
This may have been given in an earlier paragraph but maybe you could allude to or add a specific standard deviation of the change scores here

ariance of a change score
I'm unsure if this should be sigma or sigma squared given the circumstance
-
we have introduced a series of equations designed to facilitate the extraction of pre/post correlations
Is this where we would put our R function?
-
Sometimes primary
specify that these coming scenarios are no longer exact
-
Φt−1[q,ν],
put R code here (ex. qt(p=p, df=nu)
-
If the change score standard deviation is not reported, move on to Scenario 2
It ma need some new wording but I think it would be effective to put this condition beforehand
-
Using the inverse cumulative distribution function of the Student’s t distribution (
maybe mention R function qt(p=lower tail prob, df=n-1)
-
move on to scenarios that allow for an exact calculation of the pre/post correlation before using these formulas.
maybe mention this before the formula's
-
correlation
redundant
-
raw data is available
report what specific data we need
-
If the full five-number summary is n
Same sentiment as above

n. The following formula can be used to approximate the standard deviation (Wan et al. 2014, eq.
Should we make this consistent with the first paragraph such that the sample mean is first and the sample st, dev is last.
-
To approximate the mean, we can use the following formula
This may be overkill but should we show the error of estimation for this to show exactly how close the approximation is or is that something thats shown in the paper we linked?
-
confidence
Specifically 95% CI. because it is 2*1.96. Should we show the derivation for the width of the CI in terms of z quantiles in case theres a 90 or 99% CI reported?
-
some kind of standard deviatio
maybe say Pooled SD if thats an equivalent term (also, if this is the case, maybe denote it as Sp instead of S_*)

Meta-analyses
Possibly "meta_analyses, designed for synthesizing repeated -"
