The other numbers given in the question indicate very weak correlation. -.34 +.72 -.91 +.91 +.50 -.83 0 Answer a. This means that there is a 98% frequency that as variable a increases variable b will decrease. Correlation coefficient: Indicates the direction, positively or negatively of the relationship, and how strongly the 2 variables are related. Σx = the sum of x scores. −.64 . This value is a positive correlation that is strong. social-and-applied-psychology; 0 Answers. The correct answer is d. +.90. .80 C. .10 page 561 Question 13 5 / 5 pts Which of the following tests is essentially a comparison of means? The closer a coefficient is to 0, the weaker it is. A. The following table illustrates this effect. On a scatterplot, a correlation coefficient of .00 appears as a? On a scatterplot, a correlation of -1.00 appears as a, straight line that slopes downward to the right. Correlation statistics can be used in finance and investing. a. -.90 Correct answer to the question Which of the following correlation coefficients represents the strongest relationship between two variables? When the coefficient of correlation is 0.00 there is no correlation. https://quizlet.com/244461824/py-355-chapter-78-quiz-flash-cards if r² = 0, then you have no correlation. Most correlational research satisfies which of the following criteria for determining causality? Q 14 Q 14. Use the below Pearson coefficient correlation calculator to measure the strength of two variables. +1.22 B. the proportion of variance in one variable that is accounted for by another, A correlation coefficient of a given magnitude is more likely to be statistically significant when, it is based on a large rather than a small number of scores. Free. a. The correlation coefficient is 0.70 rather than 0 because here the curve is not symmetric. Answer and Explanation: The correct answer is d. +.90. Answer Save.
