Variables in Communication Research

What are variables in communication research?

• Specific aspects of events that change

• Specific aspects of events that remain constant

• Specific aspects of events that are irrelevant

• Specific aspects of events that are unknown

Variables can be manipulated and measured

• True

• partially true

• Don't know the answer

Choose any variable that could be measured or manipulated (a)   ​ (b)   ​ (c)   ​ (d)   ​

• Language
• Speech
• Articulation
• Phonology
• none of the above

What is a dependent variable?

• The cause of the observed effects

• An event or aspect that needs to be researched and explained

• A variable that is manipulated by the scientist

• A variable that is measured and monitored indirectly

Identify the dependent variable:

Methods in Stuttering therapy for desensitizing the parents of children with stuttering

• Stuttering therapy

• Desensitization of parents

• Children with stuttering

• None of the above

Identify the dependent variable: Title- Role of executive function in d​developmental speech fluency disorder (a)   ​ ​

• developmental speech fluency disorder
• executive function

Identify the dependent variable: Perspectives of voice treatment for unilateral vocal cord paralysis

• Voice treatment

• voice problem

• fundamental frequency

• none of the problem

How are dependent variables obtained in research?

• By breaking down broad constructs into measurable aspects

• By directly manipulating the variables

• By isolating and controlling the sources of variability

• By observing and measuring naturally occurring events

Dependent variables could be directly manipulated by the scientist

• True

• Partially True

• Partially False

• False

What is an independent variable?

• The effect that scientists study

• The cause of the observed effects

• A variable that is manipulated by the scientist

• A variable that is measured and monitored indirectly
