PSYC 3003 Week 5 Test

PSYC 3003 Week 5 Test 1. In an experimental design, the group that is not exposed to the manipulation of the independent variable is known as which of the following? 2. Which of the following provides a visual image of the relationship between two quantitative variables? 3. A repeated-measures design refers to which of the following? 4. The Pearson product moment correlation coefficient is used to assess the association between 5. When the light level of a computer screen is moderate, task performance scores are high. When the light level of the computer screen is either very low or very high, task performance scores are low. The relationship between the light level and performance is 6. A researcher found a positive correlation between income and job satisfaction in a sample of 100 adults. The researcher should conclude that 7. When conducting statistical analyses in an experimental design, in order to confirm the research hypothesis, the researcher hopes that which of the following is true? 8. The goal of random assignment to conditions is to 9. One difficulty of repeated-measures designs is that, due to the possibility of fatigue, practice, or carryover, the researcher may need to use 10. Which of the following variables affects only the outcome variable but not the predictor variable? 11. An experimenter studies the influence of ingesting sugar on memory. Children are randomly assigned either to eat a low calorie ice cream cone (low sugar condition) or a Ben and Jerry’s cone (high sugar condition). They are then asked to learn 10 vocabulary words that they did not previously know, and the number of trials it takes to learn them is measured. The independent variable in this experiment is 12. Consider the following relationship between violent material and aggressive behavior: Violent TV arousal aggressive behavior. In this case, arousal can be described as a 13. Reciprocal causation occurs when 14. An experimenter studies the influence of ingesting sugar on memory. Children are randomly assigned either to eat a low calorie ice cream cone (low sugar condition) or a Ben and Jerry’s cone (high sugar condition). They are then asked to learn ten vocabulary words that they did not previously know, and the number of trials it takes to learn them is measured. The dependent variable in this experiment is 15. In an experimental research design, the research hypothesis is that 16. The level of the independent variable in which the situation of interest was created is frequently known as which of the following? 17. A scientist hypothesizes that divorce can lead to depression and that depression can then lead to poor physical health. In this case, depression can be considered 18. Which of the following is a table showing the correlations of many variables with each other? 19. In general, are more problematic than because they can produce spurious relationships. 20. The difference between the t test and the F test is that 21. The goal of the ANOVA is to 22. Having more than two levels of the independent variable is necessary to 23. Which of the following statements is true? 24. In order to compare the means of levels of task performance when mood state is manipulated experimentally, a researcher would likely use which of the following statistical tests? 25. Experimental designs are called one-way designs if they have 26. Eisenberger, Lieberman, and Williams (2003) studied the extent to which being excluded by others created brain responses similar to those created by physical pain. The participants, who were all studied while they were in an fMRI scanner, first experienced a baseline session, then a session in which they were included in a game, and then a session in which they were excluded in a game. Which of the following designs was used? 27. A researcher is studying the relationship between a person’s gender and his or her preference for three new premium television channels. Each participant is asked to choose the one channel that he or she prefers. The researcher will use which of the following statistical tests? 28. Which of the following statistics are used to show the relationships between variables in a path analysis? 29. Which of the following is an advantage of experiments? 30. An experimenter conducts a study in which participants are randomly assigned to study in either a quiet condition or a noisy condition before their learning is tested. This research design has
