Reliability and validity are fundamental concerns

Reliability and validity are fundamental concerns when it comes to evaluating measures. a. What is reliability? Why is it important? b. The reliability of measures comprised of multiple items can be estimated mathematically (e.g., Cronbach's Alpha) by looking at how similarly each person responded to each item in the scale. Higher levels of reliability occur when each person answers the items similarly. Using that approach, the reliability for the extraversion scale is estimated to be 0.83. The neuroticism scale reliability is .67. Which scale is more desirable in terms of its reliability? Why? c. What is one strategy that can be employed to increase the reliability of a measure? Are there any potential downsides associated with such an approach
