WattsSEDU7006-8-7 NORTHCENTRAL UNIVERSITY ASSIGNMENT COVER SHEET
For your research project, you are required to design a study that investigates how the presence
of a webcam during an online live virtual classroom (LVC) session impacts learner satisfaction.
In your response, address the following points:
1. Define and discuss the concepts of internal and external validity in the context of your
study, explaining how they relate to your research question and design.
2. Describe the statistical power analysis you conducted for your sample size, including the
effects of sample size, significance level, and power on the results. How do these factors affect
the reliability of your findings?
3. In your experimental design, consider two scenarios: one with a single independent
variable (webcam usage) and one with two independent variables (webcam usage and technology
type). Describe how the factorial design will allow you to investigate both main and interaction
effects.
4. Explain the use of random selection and random assignment in your study. Why are
these strategies important, and how do they contribute to the internal and external validity of
your research?
5. Discuss the strengths and limitations of your study, specifically focusing on the
implications for generalizability and the potential for making causal claims.
