The phrase "also observed a large" is correct and usable in written English.
It can be used when discussing findings or results in a report or research context, particularly when adding additional observations to previous statements.
Example: "In addition to the previous findings, we also observed a large increase in user engagement over the last quarter."
Alternatives: "additionally noted a significant" or "further observed a considerable".
