What is the meaning of weak correlation?
Weak correlation refers to a statistical relationship between two variables that is not strong, indicating that changes in one variable do not reliably predict changes in the other. This is typically represented by a correlation coefficient close to zero, suggesting that the variables may be related, but the connection is minimal and may be influenced by other factors. In practical terms, a weak correlation implies that the association is not strong enough to draw firm conclusions about their relationship.
When a graph does not have any clear trends it probably means that the variables are what?
When a graph does not show any clear trends, it likely indicates that the variables are either unrelated or have a weak correlation. This lack of a discernible pattern suggests that changes in one variable do not consistently affect the other. Additionally, it may imply that other confounding factors are influencing the relationship between the variables.
When two variables are not related the correlation coefficient?
When two variables are not related, the correlation coefficient is close to zero, indicating no linear relationship between them. This suggests that changes in one variable do not predict changes in the other. A correlation coefficient can range from -1 to 1, with values near zero demonstrating weak or no correlation.
What does correlation coefficient of 0.15 indicates which type of relationship between variable?
A correlation coefficient of 0.15 indicates a weak positive relationship between the two variables. This means that as one variable increases, there is a slight tendency for the other variable to also increase, but the relationship is not strong or consistent. It suggests that other factors may be influencing the variables, and the correlation is not significant enough to imply a definitive link.
When the points on a graph tend to scatter randomly we say they indicate?
When the points on a graph scatter randomly, they indicate a lack of correlation between the variables being plotted. This randomness suggests that changes in one variable do not predict changes in the other, reflecting a weak or nonexistent relationship. Such a pattern can imply that other factors may be influencing the outcome, or that the variables in question are independent of one another.

In practical terms, a weak correlation implies that the association is not strong enough to draw firm conclusions about their relationship.
What would a strong association but weak correlation look like?
If the form is nonlinear (like if the data is in the shape of a parabola) then there could be a strong association and weak correlation.
Which correlation coefficient indicates the weakest relationship between variables?
Pearson's Product Moment Correlation Coefficient indicates how strong the relationship between variables is. A PMCC of zero or very close would mean a very weak correlation. A PMCC of around 1 means a strong correlation.
What does -0.285 correlation means?
It means you have a slight negative correlation between the two variables of interest. As one increases the other decrease and vice versa, albeit in a weak fashion.
Correlation coefficients represents the WEAKEST relationship?
A correlation coefficient represents the strength and direction of a linear relationship between two variables. A correlation coefficient close to zero indicates a weak relationship between the variables, where changes in one variable do not consistently predict changes in the other. However, it is important to note that a correlation coefficient of zero does not necessarily mean there is no relationship between the variables, as non-linear relationships may exist.

This suggests that changes in one variable do not predict changes in the other. A correlation coefficient can range from -1 to 1, with values near zero demonstrating weak or no correlation.
Does no pregnancy happen due to weakness?
No - There is no relationship between weakness and pregnancy. There are innumerable weak women in poor countries who conceive almost every year. However, there is a close association between weakness and the improper growth of the fetus of the unborn child.
What is correlation What are the different types of correlation Why is it important to determine correlation What does it mean when it is said that two variables have no correlation?
A correlation is the relationship between two or more variables. Correlations are described as either weak or strong, and positive or negative. There can be a perfect correlation between variables, or no correlation between variables. It is important to determine the correlation between variables in order to know if and how closely changes in one variable are reflected by changes in another variable. This is done by determining the coefficient of correlation (r), which describes the strength of the relationship between variables and the direction. -1 ≤ r ≤ +1 if r= +1 or -1, there is a perfect correlation if r= 0 there is no correlation between the variables. a value closer to + or - 1 demonstrates a strong correlation, while a value closer to 0 demonstrates a weak correlation. a + value demonstrates that when one variable increases the other variable increases, while a - value demonstrates that when one variable increases the other variable decreases. However, it is very important to understand that correlation is not the same as relationship. Consider the two variables, x and y such that y = x2 where x lies between -a and +a. There is a clear and well-defined relationship between x and y, but the correlation coefficient r is 0. This is true of any pair of variables whose graph is symmetric about one axis. Conversely, a high correlation coefficient does not mean a strong relationship - at least, not a strong causal relationship. There is pretty strong correlation between my age and [the log of] the number of television sets in the world. That is not because TV makes me grow old nor that my ageing produces TVs. The reason is that both variables are related to the passage of time.
What does correlation coefficient of 0.15 indicates which type of relationship between variable?
A correlation coefficient of 0.15 indicates a weak positive relationship between the two variables. This means that as one variable increases, there is a slight tendency for the other variable to also increase, but the relationship is not strong or consistent. It suggests that other factors may be influencing the variables, and the correlation is not significant enough to imply a definitive link.
What is an example of weak positive correlation?
An example of weak positive correlation would be the relationship between the amount of time spent studying for a test and the grade achieved. While there may be a slight increase in grades as study time increases, the correlation is not very strong. This means that studying more does not guarantee a significantly higher grade, but there is still a positive trend between the two variables.
