    Standard error calculation for more than one sample size

    Hi all I am conducting a meta analysis of pearsons r correlations. Whenever a study has presented more than one correlation I have averaged them into one correlation by converting them into fishers z scores. I now have the problem that I need to calculate a standard error and variance of the...

    calculating standard error and variance of correlation estimates

    Hi all I understand that to calculate the standard error of correlation estimates converted into fishers z scores you need to follow - 1/(√N−3) Now I have the standard error , I am wondering how I calculate the variance please? Thanks

    Converting spearmans r to fishers z for meta analysis ; Correcting for range in meta analysis

    Hi all I am conducting a meta analysis of pearsons r correlations but I have a study with a spearmans rank correlation. I was converting the pearsons correlations into fishers z scores to conduct the meta analysis , then to be converted back into correlations, but I am wondering if I am able to...

    Paired Sample T-Test, Bivariate Correlation, Factors Influencing Resistance to Change

    Hi there, My study investigates factors that influence resistance to change in an organisation. The independent variables are: trust, communication, age and participation. For the purpose of this study, the target population (N=25) answered self-administered questionnaires, using a...

    Can correlation be used as a measure of accuracy?

    I have a paired data set of known age and estimated age, and correlation tests show that there is a strong correlation between the two, but what I want to know is, does that mean the estimates are accurate? My thinking is no, correlation cannot tell you if the estimated age is accurate, but...

    Pearsons correlation, confidence intervals, bootstrapping... Statistical nightmare

    I am currently running a project where I have 4 variables and a questionannaire with 4 subscales. I have performed a Pearsons correlation on this (due to high frequency of extreme scores in the questionairre and non-normal distribution of the questionnaire) and have found 2 significant results...
