    Effect size in regression

    Hi Noetsi, thanks for your reply. I have a doubt on your (and Hlsmith) comment: You both coincide when suggesting that the authors of this report might be trying to standardize the slope coefficient. However: 1) if that would be the goal, would it not be achieved when dividing by the standard...

    Effect size in regression

    Hi hlsmith, Thanks for your answer. Unfortunately, the methods section is very short and table/ figure legends do not provide further details. Let's see if anyone else has seen this procedure before and can provide further details. In any case, your answer is very much appreciated

    Effect size in regression

    Hi everyone, I am reading an article at which authors used an effect size that it's totally new to me and I do not know how to interpret it. I would appreciate if anyone could explain its meaning or provide any reference about its interpretation. Below, I paste some sentences from the original...

    Local association measures

    Hi everyone, I have read that there are local measures of association to be used when wanting to conduct a finer-grain analysis of an X-Y association (Grissom and Kim, pages 101-102). However, this comment is framed in the context of two continuous variables and I wondered whether these local...

    Percentages and statistical significance

    Hi Sh7, I am not a stats expert but, perhaps, my comments would be useful to you. If I understood properly, you want to compare two proportions (you do not need to transform them to %): The proportion of false memories in the condition "distractor" and the proportion of false memories in the...

    effect size

    Hi Moyu, Interpretation of effect size is always context-dependent. In clinical contexts, even small effects might be important. This is easy to understand if the treatment being tested is actually saving lives (i.e. only one 1% more of efficacy could save the life for thousands of people!) If...

    How to summarize a pattern of correlations?

    Hi, I have performed a small memory study at which participants could commit two types of errors (false positives and false negatives; F+ and F-) in four different stimuli categories. I have observed that the two kinds of errors (F+ and F-) for two stimuli categories show a reciprocal pattern...

    reporting chi-square in 2x3 contingency table

    Hi Karabiner, thanks a lot for your reply. I am happy to be corrected when I still have the opportunity to do things properly. However, if I may, I would like to ask for a little bit more help here. I assume that I should just calculate means of A, B, C and then compare them by a MANOVA... would...

    reporting chi-square in 2x3 contingency table

    Hi everyone, I am conducting an experiment and I have two groups of participants (controls/ treated; 50 each). For each participant, I performed 40 measures with 3 possible outcomes (A, B, C) and recorded the accumulated frequencies (for example: control1: 10A, 20B, 10C; Control 2: 20A, 10B...

    how to automatically repeat the same analysis

    Hi obh, I am using chrome and what I did was break down my analysis to batches of 50 dependent variables at the time. It worked nicely and it repeating the process four times was 50 times better than having to eat 200 times ;) Of course, this kind of analyses should be handled with powerful...

    how to automatically repeat the same analysis

    Hi obh, thanks a lot. I am not sure if I explained myself right. So, I attach an snapshot from SPSS output and indicate there what I meant about standardized coefficients. Seems I am using SPSS in Spanish, I added some labels by hand. One more time, thanks for all your help and patience. :-)
