I created a survey with 3 embedded experiments (from the library). I downloaded the zip file with results so far and I can see info such as individual RT and error rates in the text files (but not in the excel files, as far as I can tell), but no info on median/mean results, which is what I really need. I read in the instructions that in order to get those data I need to specify the parameters in the analyze section. I watched the tutorial on how to do that, but the steps in the video don't match what happens on my screen. (the video is for individual experiments, but when I go to each of my individual experiments in the left side bar, it shows no files to work with and mean/median are not listed as options in the list of parameters anyway).
I am completely new to research and coding and so far so good, but I'm hitting a wall here. Thanks in advance!

Hi there, instead of using the analyse section of PsyToolkit you could use R in order to calculate the mean and median of your data of interest. Here you can find some information on how to use R with data from PsyToolkit: www.psytoolkit.org/lessons/startingwithr.html |

Hi Alexandra, thanks for your response! I checked out the link and it looks very doable to learn R. But it looks like I would still have to type in each individual value to get the mean. I have about 100 respondents so far, who each do 3 tests with about 30 responses each. So that's almost 1,000 RTs I'd have to type in. I was hoping there was a way to get those means automatically and it sounded to me like that's what the Psytoolkit analyze function was offering. Or am I wrong and is massive data entry why researchers have all those graduate assistants? :-)

Update: I went back to the analysis section and was able to analyze the data for one participant and get the means as well. So I think I'm good to go now for the rest of my data. Thank you for pointing me to R, though; I think I'll download that and learn it because it looks like a great tool for what I'm trying to do.

Great to hear that it seems to work for you now. In R you will not need to type each number by hand. For reading txt-files into R the function "read.table()" is very useful, because this allows you to load all data of each txt-file and assign it to a variable. Using the data frame, which your variable is now, you can then calculate the mean by calling the column containing your reaction times. This forum is not suited for teaching R, so my explanation might not mean anything to you yet, but as soon as you have looked at R a bit more, this might help you a bit. Good luck with your research.

Hello! I had the same problem for a long time but then I discovered that I had entered wrong columns in the data analysing option. There is also a turtorial about it here but I tell you how to get there step by step: Click on your experiment under "edit experiments", then click on the link under "Analyze". Choose one individual txt file and upload it. Now the important part is "Set the meaning of the columns in data file", if you put the right numbers of columns then you get means of those parameters in the output excel file, that is the key! Pay attention on the grouping variables, because they are the ones that you get the means of in the output file. Check if everything works and if you get the means of the parameters you wanted by clicking on "Save parameters and run analysis on the selected file". If everything works then go back to your study and download the zip file again(now with the right means). I hope this helped, it did for me  |

Thank you so much for such a step-by-step explanation. I followed what you recommended, I also went through the stages in the tutorials as well as the column information given on the website for my selected experiments, but I still haven't been able to get the R stats. I am using the Stop Signal and the Deary-Liewald tasks (from the library). I tried different columns for grouping but nothing has worked, I don´t know what I am doing wrong. Any chance you could any further advise, please? Thank you in advance! Amna |
