In this discussion you're going to come up with your own research scenario. This must be your own original study idea.

1- Create a "Example Experiment" similar to the questions and example below. This can be about any topic you want.

When you come up with your "Example Experiment" try to figure out the null and alternative hypotheses, and what the type I and type II errors would be in those situations.

Here's an Example to give you an idea about what you'll be doing: A researcher is interested in testing whether a new therapy for adolescent depression works to reduce depression. He measures depression before and after the therapy and he expects depression levels to decrease after therapy.

Hypotheses:

Null Hypothesis: H₀: depression after therapydepression before therapy (in other words, depression is the same or worse after therapy than it was before therapy);

Alternative Hypothesis: H₁: depression after therapy < depression before therapy (in other words, depression is lower after therapy than it was before). This hypothesis is directional

• Type I error: The researcher concludes that depression decreases after therapy, when in reality depression is the same or worse after therapy (in other words, the researcher concludes that the therapy works to reduce depression, when in reality it did not!).
• Type II error: The concludes that depression levels are the same after therapy, when in reality they get better (in other words, the researcher concludes that the therapy did not work to reduce depression, when in reality it did!)
