What is the appropriate research design for studying the relationship between outside temperature and ratings of happiness?1 分CorrelationalExperimentalQuasi-experimentalDescriptive

The appropriate research design for studying the relationship between outside temperature and ratings of happiness would be Correlational.

Here's why:

1. Correlational research design is used to measure the relationship between two variables, without manipulating any of the variables. In this case, the two variables are outside temperature and ratings of happiness.

2. Experimental design would not be appropriate because it involves manipulating one variable to determine if changes in one variable cause changes in another variable. In this case, we cannot manipulate the outside temperature.

3. Quasi-experimental design is also not suitable because it also involves manipulation of variables, but without random assignment. Again, we cannot manipulate the outside temperature.

4. Descriptive research design is used to describe characteristics of a population or phenomenon being studied. It does not answer questions about how/when/why the characteristics occurred, which makes it an inappropriate choice for this study.

Therefore, a correlational research design would be the most appropriate choice for studying the relationship between outside temperature and ratings of happiness.
