In a scientific investigation, the term “quantitative data” refers to numbers that are usually followed by

...

a unit that is well defined.

So if I told you I will give you 100 ---

is that great or is that terrible?

say it's 100 bucks - is that dollars or deer?

If I tell you something is 40 long - is that miles, mm, feet, meters...??? Knowing it is 40 tells you nothing without the units.

I always say numbers without units are useless.

Units makes a difference!
