off the top of my head - siginificantly would signify measure/size. synonym to that would be greatly. ex. firm X significantly reduced its head count = they cut a lot of people.
significant means important/relevant. these results are significant and are within the scope of our research. this variable is significant because it correlates highly with X.
maybe check thesaurus?
