What essential component increases the testability of a hypothesis?

The essential component that increases the testability of a hypothesis is the use of quantifiable words. This approach allows researchers to clearly define variables in measurable terms, which facilitates empirical testing and statistical analysis. When a hypothesis incorporates quantifiable measures, such as specific amounts, frequencies, or statistical figures, it becomes possible for researchers to design experiments or observational studies that can confirm or refute the hypothesis based on concrete data.

In contrast, the other options do not promote testability. Qualitative descriptions may provide rich insights but often lack the specific metrics needed for testing. Subjective interpretations can lead to variability in understanding what a hypothesis entails, creating ambiguity that hinders effective testing. Utilizing complex jargon can obfuscate meaning, making it difficult for others to replicate the study or assess the hypothesis effectively. Therefore, clarity and measurability through quantifiable words are crucial for making a hypothesis testable.
