using hyphen


1. "As a result - significant progress was achieved."

2. "the nice property of averaging - it allows a consistent hierarchy of scales."

I was told that the sentences are odd. What is wrong, how to improve them?

 The first sentence should have a comma, not a hyphen.  You can find out about the hyphen here:

A dash is used in a sentence when you want to add something parenthetically.


Your second example is only part of a sentence, so it is impossible to tell if there should be a dash, a comma, or no punctuation.  I have no idea what a “nice property of averaging” might be.

I added the rest. Thank you for the first sentence!

The second sentence still makes no sense to me at all.

Pattry -- in addition to parenthetical uses, em-dashes may also be used as a substitute for a comma, but only were special emphasis is desired and makes sense. You are correct in that the first sentence does not offer that opportunity for emphasis (unlike my first sentence here).

Yeah, I wasn't trying to get too detailed with my answer.
