If you do not already have Google Analytics (GA) connected to your blog, please follow Google's instructions to set up GA on your site: https://support.google.com/analytics/answer/1008015
If you already have a GA-connected blog, please make sure that your GA account has all of the appropriate permissions to manage the view for this particular blog. You can do this by editing the "Admin" settings of your site on GA and ensuring that the User Management permissions for your blog is set to: “Edit, Collaborate, Read & Analyze, Manage Users” (screenshots below).
