Evaluating a World of Information by Beth Morling (4th edition)  Read pages 125-132 of Chapter 5 on Reliability of Measurement and answer the questions below:

Part 1

1. What does the reliability of a measure refer to?

2. How do researchers measure reliability? (describe the three ways of assessing reliability)

3. Educational psychologists use teacher ratings of classroom shyness (on a nine-point scale, where 1 = not at all shy in class and 9 = very shy in class) to measure children's temperament. Indicate which kinds of reliability would need to be evaluated and explain why.

3. Explain why measurement reliability is necessary, but not sufficient for measurement validity. 

Part 2  

Read pages 133-143 of Chapter 5 on the validity of measurement and then answer the following questions:

1. Consider how you might validate the classroom shyness rating example from the previous discussion post question. What does criterion validity evaluate? What behaviors might be relevant for establishing the criterion validity of the classroom shyness rating scale?

2. How would you evaluate the convergent and discriminant validity of this rating system?

3. What traits should correlate strongly with shyness?

4. What traits should correlate only weakly or not at all with shyness?

5. Explain why you chose those traits.
