The Sapir-Whorf Hypothesis combines linguistic relativity and linguistic determinism. Adherents of the hypothesis follow these two principles to varying degrees

Hypothesis Testing Hypothesis Testing In today’s world of statistical research there is a multitude of ways to make new discoveries and formulate new ideas; one way to accomplish this is for researchers to have inquiring minds that need to have their questions answered. To do this they must develop their hypothesis. Then researchers can develop a verbal and numerical hypothesis in which they will be able to test this hypothesis.

Weapons Hypothesis (NWH) suggests that invasive plant species can potentially out-compete native species due to their allelopathic (phototoxic and/or antimicrobial) chemicals. This use of “novel weapons” is usually thought of as a form of competition due to its potential to degrade the metabolism of neighboring plant species. Because native plants have not previously encountered the toxins released from the invasive allelopathic species‚ they have no evolved defences. The Novel Weapons Hypothesis has
