Hi,

I am having trouble when "merging" records from Arena Mobile Experiments on two different devices. Ideally, we would like to be able to collect data for the same plot on multiple tablets, upload them on mobile, and combine the attributes collected on multiple tablets. This would maintain the values from both of the tablets.

For example, currently if I collect:

(Tablet 1): "Comments" = "RED" (Tablet 2): "Comments" = "BLUE"

... when merging, the end result will be "RED". We would like it to instead be something like "RED, BLUE"

We have noticed that when the "multiple" box is checked within the "node definition", the result when merging from two data sources is that the value from the checked box attribute on the SECOND device is maintained and when the "Multiple" box is not checked, the value from the FIRST device is maintained.

Is there a way for merging to function in the desired way?

Dear user,
Merging the text attributes in the way you are seeing will be quite tricky from our side.
Instead, we can modify the way it works now for multiple attributes; if the attribute is of type code, we can keep the values from the "second" device, otherwise if it's text or numeric we can keep both values.
Let us know if it will fit your needs.
Many thanks,

Stefano,

What you are describing sounds like it will be what we are looking for. In most cases for our survey, we would like the ability to keep the values from both devices for text and numeric values.

Separately, is there a way to "send data" from two devices with the same 'key' without merging the two at the time of upload? We would like to have more control over who is doing the merging while also being able to upload the data to Arena in its raw form.

Thank you!

Hannah

Dear Hannah,
In the latest version of Arena, when you merge a multiple attribute (of type text and numeric) coming from 2 records, values from both records will be kept.
We are still working on other improvements of the merging feature, we will keep you updated.
Many thanks,
