I would be surprised if the average person knew how to install an OS. The OS generally comes with the PC so the average user never need to install an OS. I imagine the average user doesn’t even have a USB stick to turn into bootable media and that’s just the first step. You have to know how to turn it into bootable media (the easiest way expects you to already have Windows) and then if the BIOS doesn’t automatically boot into it you have to know how to go into the BIOS to change the order and then you have to get through the installation. No average user is going to get through all that. Anyone doing that is already capable of installing Linux themselves and they’re probably more willing to give Linux a try because they can always install Windows if they don’t like it.
