Review I. Variable = any trait that can change values from case to case. Must be: . Exhaustive:. . variables should consist of all possible values/attributes. Dr. Kari Lock Morgan. Describing Data:. Two Variables. SECTIONS 2.4, 2.5. One quantitative variable (2.4). One quantitative and one categorical (2.4). Two quantitative (2.5). z-score. Which is better, an ACT score of 28 or a combined SAT score of 2100?. What is correlation?. How to compute?. How to interpret?. This week. 2. The relations between two variables. How the value of one variable changes when the value of another variable changes. A correlation coefficient is a numerical index to reflect the relationship between two variables..

Or does the relationship you found in your sample really exist in the population or were your results a fluke?. Many . studies generate large numbers of data points, and to make sense of all that data, researchers use statistics that . summarize. the data, providing a better understanding of overall tendencies within the distributions of scores.
