Final answer:
Communication apprehension refers to a person's fear or anxiety about communication, while speech anxiety is specifically the fear of public speaking. In the study example, a hypothesis test aims to compare the prevalence of speech anxiety in a school to a national average. Continuous text communication can increase attachment but may weaken perceived relationship quality compared to voice conversation.
Step-by-step explanation:
The relationship between communication apprehension and speech anxiety is relevant when considering public speaking within educational contexts. Communication apprehension is a broader term referring to a person's fear or anxiety associated with either real or anticipated communication with others. Speech anxiety, also known as glossophobia, is a more specific type of communication apprehension, which is the fear of public speaking.
In the provided student example regarding a study on public speaking fears among schoolmates, the student is looking to conduct a hypothesis test to find out if the percentage of those who fear public speaking at her school is less than the national average of 40%. If we apply this to the concept of speech anxiety as a form of communication apprehension, her research could reveal useful insights into the prevalence of this form of anxiety in her school's population.
Considering the effects of communication styles in various relationships, it's important to note that while continuous messaging can increase attachment, the quality of a relationship might be perceived as weaker if it relies heavily on text messaging rather than voice conversations. Voice conversations can offer richer, more nuanced exchanges, which may be less anxiety-inducing for some individuals compared to the prospect of public speaking.
