What correlation coeficcients expresses weakest degree of relationship?
The correlation coefficient that expresses the weakest degree of relationship is 0. A correlation coefficient of 0 indicates no linear relationship between the two variables being analyzed. Values closer to -1 or +1 indicate stronger negative or positive relationships, respectively. Thus, a coefficient of 0 signifies that changes in one variable do not predict changes in the other.
If doubling the manipulating variable results in a doubling of the responding variable the relationship between the variables is a?
This would indicate that there is a linear relationship between manipulating and responding variables.
Which correlation coefficient indicates the strongest relation between two variables is it -13 or 38 or 56 or -74 which one?
The correlation coefficient ranges from -1 to 1, where values closer to -1 or 1 indicate a stronger relationship. Among the given options, -74 (interpreted as -0.74) has the strongest absolute value, indicating a strong negative correlation between the two variables. Therefore, -74 indicates the strongest relation compared to -13, 38, and 56.
What is implied when it is said that x and y have a positive correlation?
When it is said that x and y have a positive correlation, it implies that as the value of x increases, the value of y tends to increase as well. This relationship suggests that there is a direct association between the two variables, meaning that higher values of one are associated with higher values of the other. Positive correlation can be quantified using a correlation coefficient, typically ranging from 0 to 1, where values closer to 1 indicate a stronger correlation.
What does a correlation coefficient of 1.1 mean?
Well, friend, a correlation coefficient of 1.1 is not possible because correlation coefficients range from -1 to 1. If you meant 1.0, that would indicate a perfect positive linear relationship between two variables. It means as one variable increases, the other variable also increases proportionally.
Measure of how closely one thing is related to another?
This is referred to as correlation, which quantifies the strength and direction of the relationship between two variables. The correlation coefficient can range from -1 to 1, where values closer to 1 indicate a strong positive relationship, values close to -1 indicate a strong negative relationship, and a value of 0 indicates no relationship.
What does the size of a correlation coefficient indicate?
Size of variables
Does a negative correlation coefficient indicate an inverse relationship?
Yes, but the relationship need not be causal.
What is the meaning of correlation coefficient?
The correlation coefficient takes on values ranging between +1 and -1. The following points are the accepted guidelines for interpreting the correlation coefficient:0 indicates no linear relationship.+1 indicates a perfect positive linear relationship: as one variable increases in its values, the other variable also increases in its values via an exact linear rule.-1 indicates a perfect negative linear relationship: as one variable increases in its values, the other variable decreases in its values via an exact linear rule.Values between 0 and 0.3 (0 and -0.3) indicate a weak positive (negative) linear relationship via a shaky linear rule.Values between 0.3 and 0.7 (0.3 and -0.7) indicate a moderate positive (negative) linear relationship via a fuzzy-firm linear rule.Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship via a firm linear rule.The value of r squared is typically taken as "the percent of variation in one variable explained by the other variable," or "the percent of variation shared between the two variables."Linearity Assumption. The correlation coefficient requires that the underlying relationship between the two variables under consideration is linear. If the relationship is known to be linear, or the observed pattern between the two variables appears to be linear, then the correlation coefficient provides a reliable measure of the strength of the linear relationship. If the relationship is known to be nonlinear, or the observed pattern appears to be nonlinear, then the correlation coefficient is not useful, or at least questionable.
If doubling the manipulating variable results in a doubling of the responding variable the relationship between the variables is a?
This would indicate that there is a linear relationship between manipulating and responding variables.

What does a correlation coefficient represent?
The correlation coefficient for two variables is a measure of the degree to which the variables change together. The correlation coefficient ranges between -1 and +1. At +1, the two variables are in perfect agreement in the sense that any increase in one is matched by an increase in the other. An increase of twice as much in the first is accompanied by double the increase in the second. A correlation coefficient of -1 indicates that the two variables are in perfect opposition. The changes in the two variables are similar to when the correlation coefficient is +1, but this time an increase in one variable is accompanied by a decrease in the other. A correlation coefficient near 0 indicates that the two variables do not move in harmony. An increase in one is as likely to be accompanied by an increase in the other variable as a decrease. It is very very important to remember that a correlation coefficient does not indicate causality.
When your graphing what is it called when the dots are in a line?
When the dots on a graph form a straight line, it indicates a linear relationship between the variables being plotted. This alignment suggests that there is a consistent rate of change, which can be described by a linear equation. If the dots perfectly align, it might indicate a perfect linear correlation, while a scattered arrangement could suggest a strong or weak correlation.
How do you read a scattergram?
To read a scattergram, observe how the data points are dispersed on the graph. Look for any patterns or trends, such as a positive or negative correlation. Assess how closely the points cluster around a line or show a particular shape, which can indicate the strength and direction of the relationship between the variables.
What do positive values of covariance indicate?
as the covariance of the two random variables (X and Y) is used for calculating the correlation coeffitient of those variables it indicates that the relation between those (X and Y) is positive, so they are positively correlated.
What are organizational variables?
