If there is a correlation between event A and event B, it means that changes in one event are associated with changes in the other. However, correlation does not imply causation; just because two events occur together does not mean that one causes the other. It's important to consider other factors that might influence both events. Further investigation is often needed to establish a causal relationship.
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
A correlation interval refers to the range within which the correlation coefficient, a statistical measure of the strength and direction of a relationship between two variables, is assessed. Typically, this interval ranges from -1 to +1, where -1 indicates a perfect negative correlation, +1 indicates a perfect positive correlation, and 0 denotes no correlation. In practice, correlation intervals can also refer to confidence intervals around the correlation coefficient, providing a range of values that likely includes the true correlation in the population.
The statement about the correlation between the number of hours a person studies and their exam score is true; generally, more study hours lead to higher scores, indicating a positive correlation. Similarly, there is often a positive correlation between a child's age and their height, as children typically grow taller as they get older. As for the speed of a vehicle, it would depend on the context; if you're referring to speed increasing with time or distance, that could also represent a positive correlation.
Correlate means to connection one thing to another in terms of how they relate to one another. For example one could write a paper to correlate how dropping out of school leads to working jobs that do not pay well.
There isn't any correlation between gathering wealth and IQ. Many factors are involved on becoming rich and keeping themselves rich. If it was true, IQ and wealth involved, rich men would not lose their wealth never. Desire of success and power leads many persons with a medium IQ to become rich.
event B has something in common with event A
event B has something in common with event A
Event B has something in common with Event A.
event B has something in common with event A
The Matthew correlation coefficient considers true and false positives and negatives. The specificity correlation only considers the true classes or rejections.
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.

Correlation * * * * * That is simply not true. Consider the coordinates of a circle. There is obviously a very strong relationship between the x coordinate and the y coordinate. But the correlation is not just small, but 0. The correlation between two variables is a measure of the linear relationship between them. But there can be non-linear relationships which will not necessarily be reflected by any correlation.
Yes, it is true that the location of the earth's surface is directly above the focus of an earthquake is the epicenter a close correlation exists between epicenters and the plate boundaries.
True , it would have been false only if it was mentioned no relationship . But as it mentions linear it is true.
No, that is not a causative correlation.
