can you please help and answer questions on three separate assignments


Assignment 10 · Discussion Question #1 How can surveys be used to address descriptive and/or causal research questions? What are some of the advantages to using surveys to collect data? What are some of the disadvantages?   · Discussion Question #2 What can researchers do to ensure their survey is valid? Why is this important? What are the different types of validity that should be considered? What other concerns may affect validity of the survey? Assignment 11 The purpose of this activity is to emphasize that correlational studies investigate relationships between variables, but do not imply causation. Check out the examples of spurious correlations at:  http://tylervigen.com/spurious-correlations (Links to an external site.). After examining these examples, respond to the following questions: 1. What can correlational studies accomplish? 2. What type of research questions can be addressed using correlational studies? 3. Do correlational studies include dependent variables? Do they include independent variables? 4. How is a correlational study different from a quasi-experiment? 5. Why can’t we say that correlation equals causation? Assignment 14 · Discussion Question #1 What distinguishes a quasi-experiment from a true experiment? When might a quasi-experiment be more appropriate? What are some examples of quasi-independent variables?   · Discussion Question #2 Is it possible to determine causation from a quasi-experiment? How and why does the interpretation of results change?
