How do I... TRANSFORM VARIABLES in Jamovi? (2022)

How do you recode a variable into a new one? How do you reverse code a variable item so you can take the sum or average? There's a simple interface that will allow you to just that!

Thank you for clarifying this for me.

[@ewhilton]

Keep up the great work, this video series will be really helpful.

[@MrOceanson]

Thanks for the effort. Good information but I had to slow down the playback to 0.75x ...
Just something to keep in mind for future recordings! ;)

[@AlexanderSwan]

I talk too slow at normal speed, so I speed myself up. I do this because I know the playback controls exist, so if someone does need to slow me down, they can. It also makes my videos shorter, which is helpful for the algorithm.

That was great. Thanks.

Thank you for theses videos. I have a question. How can I transform a range of scores to categories? Example: transform a variable scored between 2 and 5 to category A, 5 and 8 to category B and so on. Is there a function for that?

[@AlexanderSwan]

It sounds like you want to recode variables, so that is a different function. You might want to make a new variable, sort, and do this manually. You might be able to do this using the levels tool in the variable editing window.

Thank you so much for these videos.. clear explanation and easy to follow. I have a question about jamovi. When I run the Hierarchical clustering method and start adding more than two variables, I get this message: 'x' must be numeric. Can you please help me fix this problem.

[@AlexanderSwan]

I can't fix this error without knowing what your data looks like. It could either be a user error with incorrect data or a bug (which needs to be reported to the devs)

I tried to find answear but still cant. May be you can help. I have date variables in format YYYY-MM-DD and need to transform it into YYYY, how can i do it using Jamovi?

[@AlexanderSwan]

I’m not sure Jamovi can do that transformation. You may just have to sort it and manually adjust them down the column or do the transform in Excel.

[@dr_pikirenia]

@@AlexanderSwan Thanks for your answear. I found solution. Jamovi have no Date type of variables and understand it as simple text. So you need to split date in to parts and chose part you want. In my case transformation looks like: SPLIT($source,'-',1)

[@vaishnavijagannathan3920]

hi .how to write code if its like i want to recode the variable as A if the value is between 2 and 5?

[@AlexanderSwan]

I'm not sure I understand your question. You want to change 2,3,4,5 to the letter A?

[@Ttestposs]

If we have a regroupement variable??

[@AlexanderSwan]

I’m not sure what you’re asking
