Now we will discuss dependent variables, which are the measurements taken from each subject: the data.
These are variables because each subject potentially will have different scores.
Development of a standardized operational definition of assent would thus be important to ensure that investigators, institutional review boards, and policy makers consider the assent…
In the first part you will practice providing an operational definition for a variable.
Make sure it is a measure for the correct construct.
For example, a measure called the eating disorders scale (EDS) is not a measure of depression even if it appeared in a journal article about the relationship between depression and bulimia.In the example of quadriceps strengthening, the strengthening protocol used is the independent variable, and the maximal torque generated isometrically on an isokinetic dynamometer by the quadriceps muscles is the dependent variable.Once a basic purpose or concept of a research project has been established, it is important to establish the variables that will be studied.In the second part you will answer questions about a hypothetical research design Operational Definitions An operational definition of a variable is the set of procedures used to measure or manipulate it.A good operational definition is clear enough so that an independent researcher could use the same procedure (replicate the research) and get the same results.Background There is currently no consensus from the relevant stakeholders regarding the operational and construct definitions of child assent for research.As such, the requirements for assent are often construed in different ways, institutionally disparate, and often conflated with those of parental consent.Questions: a) How might you setup an experiment to test this hypothesis? e) What is one outcome that would indicate a negative relationship between the IV and DV?(Don't worry about funding, assume you have enough to do whatever you want to plan) b) What would be the independent variable (IV)? f) What is one possible confounding variable and why might it be a confounding variable?Provide one operational definition for one of the following: Insomnia Psychosis Introversion Anxiety Quality of Life Academic achievement Intelligence Disability Variable Selected: Operational definition from a published paper: Citation in APA format: In part 2 of the assignment you will answer some questions about a hypothetical research project and demonstrate your understanding of how to state a hypothesis, the difference between the independent and dependent variables, the directions of relationships between variables, and confounding variables.Answer the questions below about an experiment you might plan to determine the extent to which drug X improves mood in depressed people.
