What is the type of research, that when studying the relationship between X and Y, cannot infer that X causes Y, or Y causes X? a. Experimental research b. Quantitative research c. Qualitative research d. Correlational research |
d. The answer is d because correlational research studies the relationship between X and Y whereas other research methods study causation. See slide 20, week 1.1. |
|
|
If the relationship between X and Y can be generalised beyond the study, the type of validity is... a. Content validity b. External validity c. Internal validity d. Construct validity |
b. The answer is b because external validity looks at the relationship between variables beyond the setting of the study. See slide 22, week 1.1. |
|
|
What kind of inference is based on scientific method, sampled under controlled conditions, and the obtained statistic is compared to a chance distribution? a. Statistical inference b. Experimental inference c. Ad hoc inference d. Correlational inference |
a. The answer is a because these are the factors that make up statistical inference. See slide 2, week 1.2. |
|
|
True or false, larger sample sizes do not adequately reflect the characteristics of the population. |
False, this is because larger sample size produces a sample statistic that accurately reflects the characteristics of the population. See slide 8, week 1.2. |
|
|
Which of these is not a characteristic of a correlation coefficient, r? a. Quantifies the direction of the relationship between two variables b. Quantifies the size of the relationship between two variables c. Is a descriptive point statistic d. Is affected by a number of factors |
c. The answer c because the r statistic is a descriptive line statistic. See slide 3, week 2.1. |
|
|
If you obtain a correlation statistic of r = .35, the correlation can be described as... a. Low, negative b. Low, positive c. Moderate, positive d. High, positive |
c. The answer is c because a statistic of r = .35 is positive in direction and represents a moderate correlation. High correlation = .50, moderate correlation = .30, low correlation = .10. See slide 11, week 2.1. |
