Is there a simple way to remove data

[jeffwllms]

I installed the accelerator via appsource. I did not chose the option to include sample data, but there is sample data anyway. For example there are contact we have never had in the system (we have never used dataverse prior so shouldn't have any contact/accounts/etc. When first installed there is a popup that says the package doesn't contain and sample data. But this doesn't seem to be the case.

is there any way to purge the sample data easily. Would removing the solution remove the sample data?
