In a single member district plurality vote system what does a candidate need to win?

In a single-member district plurality voting system, a candidate needs to receive more votes than any other candidate to win, but not necessarily a majority of the votes (over 50%). This means that a candidate can win with just the highest number of votes, even if that number is less than half of the total votes cast. This system often leads to situations where a candidate can win despite having less overall support than multiple opponents.
