# what does a correlation coefficient of 0 indicate quizlet

Question 1. Choose the correct answer below. Edited from a good suggestion from Michael Lamar: Think of it in terms of coin flips. 0 … What do the values of the correlation coefficient mean? the closer a correlation is to 1.00 (absolute value), the stronger the relationship is. If the number is close to 0 then the variables are uncorrelated. Oh no! For uncentered data, there is a relation between the correlation coefficient and the angle φ between the two regression lines, y = g X (x) and x = g Y (y), obtained by regressing y on x and x on y respectively. If the number is close to +1 then there is a positive correlation. What does a correlation coefficient (r) of 0.0 indicate. If the number is close to -1 then there is a negative correlation. (1) - 0.73 (2) - 0.11 (3) 0.12 (4) 0.35 Planning Accounting Budgeting IFRS CMA The strength of the relationship varies in degree based on the value of the correlation coefficient. weak positive correlation. a. that no relationship exists between two sets of scores b. that those who did the best on the first test did the worst on the second test c. that those who did the best on the first test were average on the second test What is the coefficient of correlation? Increases in the value of one variable are generally associated with DECREASES in the value of the other variable-e.g. Regardless of the shape of either variable, symmetric or otherwise, if one variable's shape is different than the other variable's shape, the correlation coefficient is restricted. One of the most frequently used calculations is the Pearson product-moment correlation (r) that looks at linear relationships. Correlation coefficients that equal zero indicate no linear relationship exists. It is referred to as Pearson's correlation or simply as the correlation coefficient. Negative Correlation. If the variables are not related to one another at all, the correlation coefficient is 0. Choose from 290 different sets of correlation coefficient flashcards on Quizlet. If your p-value is less than your significance level, the sample contains sufficient evidence to reject the null hypothesis and conclude that the correlation coefficient does not equal zero. O C. It indicates a non-linear relationship between the two quantitative variables. strong negative correlation. It is important to remember the details pertaining to the correlation coefficient, which is denoted by r.This statistic is used when we have paired quantitative data.From a scatterplot of paired data, we can look for trends in the overall distribution of data.Some paired data exhibits a linear or straight-line pattern. A measure of the mathematical relationship between two numeric variables, A distribution that depicts the relation between TWO variables, A graph of a bivariate distribution consisting of dots at the point of intersection of paired scores, Increases in the value of one variable are generally associated with INCREASE in the value of the other variable, Increases in the value of one variable are generally associated with DECREASES in the value of the other variable, A mathematical expression of the degree of association between two variables. A coefficient of zero indicates there is no discernable relationship between fluctuations of the variables. The correlation coefficient (r) indicates the extent to which the pairs of numbers for these two variables lie on a straight line. There is no linear relationship between the two quantitative variables. OB. As explained below In statistics, when two variables are compared, then negative correlation means that when one variable increases,the other decreases or vice versa. .A correlation coefficient indicates the _____ and the _____ of the relationship between two variables.
