Let me add a word of clarification. KoBo helps you create a form that you can deploy over the internet to a web browser or an android device using KoBoCollect. You then enter the data in the deployed form and submit your form(s). This can be done on-line or off-line, anywhere in the world, although you need to be connected initially to load the form once and then again to upload the data.
After the data has been uploaded, you go to KoBoToolbox and download the data, which is stored in an Excel format in a cloud-based server. You download the data in XLS format, open it with Excel, and then you are free to analyze it in any way that you want. KoBo also has some built-in data analysis tools.
Hope this helps.
