Ludwig's WRAP-UP

In summary, while the phrase "determined by if" appears in various contexts, Ludwig AI analysis confirms it is grammatically incorrect and should be avoided in favor of clearer alternatives. The intended purpose is to establish conditional relationships, but the phrasing creates awkwardness. More appropriate constructions, such as "determined by whether" or "based on whether", ensure clearer and more credible communication. This is especially important in formal writing contexts like scientific papers or news reports. Therefore, always prioritize grammatical correctness and clarity over sticking to this flawed phrasing.
