Five research scenarios are presented, followed by a few questions each. Please answer each question, providing enough detail from Chapter 5 to demonstrate your understanding of the material. When asked to draw a scatterplot, you can a) graph using MS Word or MS Excel or b) draw by hand and scan, take a picture, etc. and upload. My preference is that you embed this picture into a word document, but you can upload pictures to this assignment if you’ve clearly labelled it. Please upload a word document with your answers using the submission button to the right.

Scenario One: Researchers place unobtrusive video recording devices in the living rooms of 20 children. Later, coders view tapes of the living areas and code how many minutes each child spends playing video games.

1. What kind of reliability would need to be evaluated?
2. Draw a scatterplot of describe a result that would indicate that the measure has good reliability and one that shows it has poor reliability.

Scenario Two: Clinical psychologists have developed a 7-item, self-report measure to quickly identify people who are at risk for panic disorder.

1.  What kind of reliability would need to be evaluated?
2. Draw a scatterplot of describe a result that would indicate that the measure has good reliability and one that shows it has poor reliability.

 Scenario Three: A restaurant owner uses a response card with four items in order to evaluate how satisfied customers are with the food, service, ambiance, and overall experience.

1. What kind of reliability would need to be evaluated?
2. Draw a scatterplot of describe a result that would indicate that the measure has good reliability and one that shows it has poor reliability.

Scenario Four: Clinical psychologists have developed a 7-item, self-report measure to quickly identify people who are at risk for panic disorder.

1.  How might you show that this measure has criterion validity?
2. How might you show that this measure has convergent and discriminant validity?

Scenario Five: A restaurant owner uses a response card to evaluate how satisfied customers are with the food. It contains one item, "Please rate the quality of the food" on a scale from 1 (very dissatisfied) to 4 (very satisfied).

1. How might you show that this measure has criterion validity?
2. How might you show that this measure has convergent and discriminant validity?
