Once you have reversed scored items, when you go on to run other data screening analyses such as normality testing, do you use the original data that hasn’t been reversed or do you use the reversed coded items? Or is it that you only use the reverse coded items when testing for Cronbach alpha?
I figured out an easy way if you are reverse scoring for large numbers if anyone needs it (bit of common sense): Maximum = 5 / minimum = 1. I had values with infinite decimal places, so the video wasn't helpful. I just added a variable called '5' (my maximum score), and then went to 'compute variable' - my new variable SatisfactionRS (RS=reverse score). I then simply typed in '5' - 'satisfaction' - this reverse scored all of my analyses I had already done, making it easy to continue my analysis without going back over ALL of my data (a few weeks already!).
Hi Siobhan, Great video, thank you so much. How do I reverse score a 0-100 scale. Do I need to apply this same rule to each number from 0 to 100 or is there a quicker way?
I was ask to use Rosengberg scale after reversing my scores---but I keep getting this message that says:there are too few cases for analysis--What did I do wrong? Help please! Thanks
Hello, after my classmate and I reverse scored our variables, which are 1-4, 11, 14, 15, some of the cells were empty with a period. Those variables where subtracted by 7 (1-4, 11, 14, & 15), is it okay to have negative numbers as the new variable? Or is that what is causing the cells to be empty after they are recoded? Thank you.
Hi Siobhan, Thanks so much for this video- it's very useful. I've reverse coded a total score variable (which is an average total score) and some has been reversed, whereas other chunks of data has ended up missing (e.g. become blank). For example, some of the data that was originally a total score of 1 was reversed into a 5, but then other participants who also had 1 as a total score were not reversed into a 5 and instead the cell has become blank. Can you think why this might have happened? Many thanks for your help, All the best, Catrin
catringriffiths1 Catrin- The only thing I can think of is maybe you had certain data selected when you ran the recode? If you had selected say only males to look at them for some reason and forgot to remove/reset the selection before you ran the recode, the recode would only take effect for the data you had selected. Hope that helps!
i accidentally rescored too many questions, how do i remove the variables i dont want rescored? and will this affect the file in a hugely negative way (i haven't calculated any thing as yet)
Jonathan Thomas Jonathan - it depends on whether you recoded into new variables or did it the quick way and recoded over your old variables. If you did it the quick I would start over with a clean version of your dataset (hopefully you saved it separately)! If you did it the safe way - recoded as new variable just delete out the ones you don't need by clicking on the variable name at the top of the column and hitting your delete key - easy as pie!
Emilia Berra Emilia-this is reverse coding. Dummy coding is typically the name given to changing things into 0s and 1s. Here is a great tutorial on dummy coding in general for UCLA www.ats.ucla.edu/stat/mult_pkg/faq/general/dummy.htm
Right into the point, no bullshit. I also love your accent, it's very clear. Great job.
Siobhan, can't thank you enough for this. I read a couple of books on this topic and became more confused. Great tutorial! Mark
You did save me, all the texts on SPSS are checked out at my university, and I was feeling a bit panicked. Thank you for uploading!!
Thank you so much for this helpful video! I wish you a wonderful day!
I like your voice. You sound so happy and satisfied with the process of basic data analysis.
Thank you so much!! You have aided in the success of my dissertation babes!!!
this video gives me a post apocalyptic feeling somehow
very clear and helpful. Cleared up my negative split-halfs correlation. thanks!
Very helpful. Thank you!
شكرا جزيلا... Meaning thank you in Arabic. To the point, simple and useful....
You're awesome! Thank you!

I’m afraid Siobhan O’Toole has passed away since the making of this video, and, despite being her daughter, I have no clue how to help you. Godspeed
Thank you so much!! Major help!
thanks, saved a lot of time.
Kindly make a video about mediation analysis

So useful! Thank you!
really helpful, thank you!
Thx, it was very usefull
Do we need to delete the old variables once they have been reversed?
I was ask to use Rosengberg scale after reversing my scores---but I keep getting this message that says:there are too few cases for analysis--What did I do wrong? Help please! Thanks
So once we get the new reversed variable in this case RHIF8r will the original RHIF8 be useless?
Basically yes, you won't use it for anything after you transform it.
Thank you so much!

Siobhan O'Toole recoded in to different variables. thanks!!!
is this dummy coding or reverse scoring? I'm confused as it seems this looks/sounds more like dummy coding...?

Thanks Siobhan. I'll keep it in mind for honours!
THAAANNNKKK YOUUU
I feel concerned by the fact that there are two pointers on the screen.
also thanks
Very helpful. Thanks so much!
Thank you so much!
Thank you!
