Detailed explanation-1: -Researchers who hope to generalize their results to a larger population should ensure that their test group is relatively large and randomly chosen. However, researchers should consider the fact that test populations of over 10, 000 subjects do not significantly increase generalizability (Firestone, 1993).
Detailed explanation-2: -Which of the following research methods would allow the researcher to conclude that there is a causal relationship between the two variables? Experiment, because an experiment is the only research method that can accurately prove cause and effect.
Detailed explanation-3: -Researchers use a measurement known as the p-value to determine statistical significance: if the p-value falls below the significance level, then the result is statistically significant. The p-value is a function of the means and standard deviations of the data samples.
Detailed explanation-4: -A researcher is LEAST likely to find a positive correlation between freshman grade point average (GPA) and: Weekly alcohol consumption. After the events of 9/11, a friend suggests that the CIA and FBI should have foreseen the likelihood of this act of terrorism.
