What Does A Positive Covariance Mean? Covariance measures the directional relationship between the returns on two assets. A positive covariance means that asset returns move together while a negative covariance means they move inversely. What do positive values of covariance indicate? Covariance mainly represents the direction of relationship of two variables. A positive sign of
What Is The Possible Direction Of Causality When Two Variables A And B Have A Strong Linear Correlation? When is the correlation coefficient zero? What is the direction of causality when two variables, A and B, have a strong linear correlation? All of the above are possible. What does independence mean in the Chi-Square Test
What Relationship Is Shown By A Straight Line Through The Points On A Scatter Graph? When the data points form a straight line on the graph, the relationship between the variables is linear, as shown in Chart 5.6. What does a straight line on a scatter plot mean? A scatterplot displays a relationship between two
When The Values Of Two Related Variables Increase Together Or Decrease Together It Is An Example Of? A positive correlation is a relationship between two variables such that their values increase or decrease together. Which of the following is used to plot the points for two variables that may be related to each other in
Which Of The Following Is The Best Example Of A Positive Correlation? A positive correlation exists when two variables move in the same direction as one another. A basic example of positive correlation is height and weight—taller people tend to be heavier, and vice versa. Which of the following is an example of a positive
How Do You Know If A Variable Is Related? In other words, knowing the value of one variable, for a given case, helps you to predict the value of the other one. If the variables are perfectly related, then knowing the value of one variable tells you exactly what the value of the other variable
Why Is Correlation Analysis Used In Research Studies? Correlation analysis in research is a statistical method used to measure the strength of the linear relationship between two variables and compute their association. … A high correlation points to a strong relationship between the two variables, while a low correlation means that the variables are weakly
What Is The Correlation Between Two Independent Random Variables? Correlation measures linearity between X and Y. If ρ(X,Y) = 0 we say that X and Y are “uncorrelated.” If two variables are independent, then their correlation will be 0. Can two variables be correlated? The statistical relationship between two variables is referred to as their
What Type Of Relationship Occurs When One Variable Decreases While The Other Variable Increases? A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases. What type of relationship occurs when one variable decreases while the other increases? A positive correlation exists when one variable
What Will Be The Correlation If Two Variables Oppose Each Other? When two related variables move in opposite directions, their relationship is negative. When the coefficient of correlation (r) is less than 0, it is negative. What is the correlation between two variables? The statistical relationship between two variables is referred to as their correlation.
