What does 调查 mean?
调查 (diàochá) works as both a verb ('to investigate, to survey, to look into') and a noun ('an investigation, a survey, a study').
It combines 调 (diào, 'to transfer/deploy/look into') and 查 ('to check/examine'). It covers police or official investigations of a case, market and opinion surveys, academic field studies, and any systematic gathering of facts. It is neutral in register, leaning slightly formal, and common in news, business, and official contexts.
Two differences from English: the same word 调查 serves as both verb and noun with no change in form, so 做一个调查 ('do a survey') and 调查这件事 ('investigate this matter') use one word; and note 调 here reads diào, not tiáo. Compare 研究 (to research/study in depth) — 调查 emphasizes fact-finding and data collection, while 研究 emphasizes analysis and deeper study.
Character by character
Memory hook: 调 (deploy/look into) + 查 (check) — deploy resources to check the facts: investigate.

Synonyms
研究 means 'to research / study' with emphasis on deep analysis and understanding. 调查 emphasizes gathering facts and data on the ground. You 调查 to collect information, then 研究 to analyze it.

检查 means to inspect/check something for problems (检查身体 medical check, 检查作业 check homework). 调查 means to investigate a matter or survey to gather facts. 检查 verifies; 调查 uncovers.
When 调 reads tiáo it means 'to adjust / mix' (调整 adjust, 调味 season). In 调查 it reads diào ('to look into'). Correct reading is diàochá, not tiáochá.
