... What type of correlation describes the following sentence: ... Q. Estimate the correlation coefficient for this scatterplot. the strength; direction of the relationship. related. best friends. Correct answers: 1 question: Which of the following correlation coefficients represents the strongest relationship between two variables? How do values of the correlation coefficient correspond to different data sets? Britannica defines it as the degree of association between 2 random variables. r is often denoted as r xy to emphasize the two variables under consideration. Correlation measures the strength of how two things are related. In statistics, correlational analysis is a method used to evaluate the strength of a relationship between two numerically measured, continuous variables. A critical thinker would most likely say, "What I need to know most is _____ whether the source is an authority." Two things should be noted. r = -0.9. r = 1. r = 0.9. r = -1. A correlation coefficient of 1 or -1 shows that the... See full answer below. Pearson coefficient is a type of correlation coefficient that represents the relationship between two variables that are measured on the same interval. answer choices . Correlation Coefficient: The correlation in statistics tells us about the strength of a linear relationship between two variables. Describe the relationship between two variables when the correlation coefficient r is one of the following. A correlation shows that two things are. The strength of the relationship varies in degree based on the value of the correlation coefficient. causing each other. 1) A correlation coefficient represents how strong the relationship is between two variables. 2. more Benchmark for Correlation Values First, correlations even as high as 0.6 don't look that different from correlations of 0. The correlation coefficient for these data is also very close to 0, being -.05. A graph represents the relationship between psychological arousal (the x-axis) and performance (y-axis). What type of relationship is this? The individuals perform better when they are moderately aroused than when arousal is either very low or very high. The annual profits for a company are given in the following table, where x represents the number of years since 1992, and y represents the profit in thousands of dollars. Correlation coefficient is used to determine how strong is the relationship between two variables and its values can range from -1.0 to 1.0, where -1.0 represents negative correlation and +1.0 represents positive relationship. a sample; strength. answer choices . For example, a value of 0.2 shows there is a positive correlation between two … the direction; a cause. unrelated.
