Disclaimer: English Kinda Thing

The sole purpose of the "English Kinda Thing" is to document my attempts to correct my own mistakes in standard English usage and to share the resources I find. In no way do I attempt to teach nobody English through these blurbs--just as I intend not to teach nobody to be a neurotic and psychotic handicap in Ratology Reloaded or Down with Meds! :-)

Creating a weighted average effect size

The following link gives you an idea about how to calculate the weighted average effect size.


Essentially, you need to have information on effect size r and the sample size

Say following is what your data looks like:
For effect size 1: r1=0.72, n1=21
For effect size 2: r2=0.53, n2=43
For effect size 3: r3=0.67, n3=44

The weighted average effect size
= 67.39/108
=0.623981 (0.62)

Of course you can go up to effect size n and I can put it all the way to the nth except for...

(A nice song to break your from the tiring pursuit towards  a weighted average effect size)
At the same time, if you are like me started from Cohen's d, you would have to convert Cohen's d into r.


While Becker's effect size calculator might come in handy, if you need to do a whole lot of conversions, you might consider simply put all things into excel everything would be spitted out in split second with one paste...

If this case, you would need to understand a secret code on Becker's page...

This question mark hidden inside of a black diamond... apparently indicates..."squart root." 8-O lol

Bon chance.

Let me know shall you have any question.

(Wouldn't love to make the algorithm etc looking for beautiful except for... a bit too tired for the day.  Sorry.)

A cheatsheet on reporting Stats APA style

Need to find a cheatsheet on reporting stats APA style?  The following are good resources.

In addition, remember, if you provide stats in a table, don't put it in the text or vice versa.

Sample size Statistical Rules of Thumb

Been working with this dataset... since t-test is pretty robust and should be good enough to handle n=10, I've working with t-test with not to much hesitation.

Than, there came to the time when the sample size went down to 8 and 9, I am sort of nervous... thus... on a mission in search of the rule of thumb for the sample size...


Regardless, after recalculating the data I was working on, results of the Wilcoxon Signed Ranks Test didn't differ too much from those of the paired-sample t-tests.

Repeated measures with two within-subject variables

Getting old here... what my teachers taught me before have been sent to the warehouse somewhere on another planet.... might have been Neptune, I think.

So I was trying to figure out how to conduct a repeated measures test with two within-subject variables.

Finally, I hit the following document and, voila, now I recall.... http://frank.mtsu.edu/~dkfuller/psy629/labs/withinanova.pdf.

Thank God that both the professor and the school are 13-hour time difference away. 8-O lol

So say the Chinese, "天高皇帝遠." lol
