「ちょっと、寮生相手にアンケートでもとってみる？」「あっ、いわゆるひとつのマーケティングリサーチだな」

「、？」「、」

'Hey, shall we try taking some kind of survey of the dorm residents?' 'Ah, what you might call a market research, huh.'

Literal

''Hey, dorm-student opponent [locative-に] survey [or something-でも] take-try-[volitional-みる]?'' ''Ah, so-called one [possessive-の] market-research is-[confirmation-な]''

Casual collaborative planning. いわゆるひとつの ('what you might call a kind of') is a slightly jocular/inflated phrasing that comically elevates the everyday activity. 相手に ('with, toward, against') marks the subject of an activity done TO someone. ~でも ('or something') softens the suggestion. ~てみる ('to try doing') is the experimental auxiliary. マーケティングリサーチ is standard loanword business vocabulary.
