Any time you compare two averages, you are doing statistics, whether or not you report the result in statistical terms. It's not something optional that you can "add on" to provide extra information. If you don't provide some measure of significance, I'm not going to trust that your result has any chance of being real. At best, you don't really know whether the result is real because you ignored the statistics; at worst, you ran the statistics and know it's not real, and you're hoping I won't notice.
