Understanding Research Design

The Thread –  Explain the two following concepts of research design.

• List and discuss the three criteria for establishing causality.  Provide examples for each. (300 words±)
• What is internal validity, and why does it matter?  Provide an example.  (100 words±)

Apply your understanding of the topics thoroughly.  Your initial thread should be ≥350 to ≤450 words (see Notes).  Ending your Thread with a question is a good way to promote active discussion.  

For each prompt, include a personal example or an example you find in a reliable publication (see Notes).

Post your initial Thread and attach a Word document of your work (see Notes).

The Replies – Each reply (x2) must be 100 to 200 words (see Notes).

You are required to write substantive replies to a minimum of two of your classmate’s initial thread.  In contrast to superficial replies, substantive replies add value to the discussion, enhance learning, and contain references to any new concepts or ideas presented.

The following suggestions will aid you in successfully composing substantive responses:

• Compare/contrast the findings of others with your research or experience.
• Compare how the findings of others enhance to the concepts learned in the required readings.
• Share additional knowledge regarding the topic that relates to the thread.

Solution – Understanding Research Design

Causality and Internal Validity

Research design helps researchers plan how to test their ideas and find answers. Two important concepts in research design are causality and internal validity, which ensure that the study’s results are reliable and meaningful.

Criteria for Establishing Causality

To show that one event causes another, researchers must meet three key criteria:

1. Covariation: This means that the cause and effect must happen together. When the independent variable changes, the dependent variable also changes. For example, if a new law is passed (the cause) and crime rates go down (the effect), we can see that the two variables are related.
2. Temporal Precedence: The cause must come before the effect. To prove this, researchers show that the independent variable happens first, followed by … Please click on the Icon below to purchase the full answer at only $5
