1. A speedometer that is always fast by 10 MPH would be __________ in validity and __________ in reliability.
2. A speedometer that is always accurate would be __________ in validity and __________ in reliability.
3. If my speedometer is always fast by 10 MPH and I am conducting research that uses speed as a DV, then the inaccuracy of my speedometer is going to lead to __________ error.
4. Since my speedometer is broken, I want to measure speed by having 5 people watch my car and then make judgments about its speed. The extent to which these people agree on my speed would be ____________________, which is quantified by the Greek letter ________.
5. If I buy a new speedometer that only measures speed from 40-100 MPH, it would be considered low in ____________________.
6. Eventually, I give up on the speedometer idea and switch my research hypothesis to the question of what type of person tends to engage in risky driving behavior. I come up with a 10-item scale to measure this tendency. The extent to which these items are correlated with each other determines the scale's ____________________, which is quantified by the Greek letter ________.
7. The extent to which this scale measures the conceptual variable of interest, risky driving tendencies, is referred to as ____________________.
8. If I can infer the level of the answer to #7 just by looking at the scale, it would be high in ____________________.
9. When participants take my scale twice within the same week, their scores tend to change drastically from one sitting to the next, suggesting the scale is low in ____________________.
10. High scores on my scale do correlate with actual risky driving behavior, which means my scale is high in ____________________.
11. Finally, my scale tends to be correlated with other scales that measure risky driving behavior, meaning that it is high in ____________________. But the fact that my scale also correlates with scales unrelated to risky driving means that it is low in ____________________.
