Depends what you mean, scoreboard is not the thing think i think you meant, i believe you meant a sidebar (Think on the side of your screen with information etc)

Plugins You can use:
Skript (NOT RECCOMENDED, YOU HAVE TO START THE CODE YOUR SELF)
A bit other ones, that you may find but ive used those too but i reccomend featherboard. Then to change it you just change the config!
If you meant scoreboard not sidebar, then /scoreboard objectives create <name> <type>
