What is the range of correlation coefficient and what does its value tell?
The product-moment correlation coefficient or PMCC should have a value between -1 and 1. A positive value shows a positive linear correlation, and a negative value shows a negative linear correlation. At zero, there is no linear correlation, and the correlation becomes stronger as the value moves further from 0.
What does a graph of Charles law shows the relationship between?
A graph of Charles Law shows the relationship between temperature and volume of gas.
Which graph shows a positive correlation between x and y?
Any graph where, from left to right, the slope goes upward (assuming the axes are labelled in the standard way).
What is a diagram that shows the relationship of elements in the domain to the range of a function?
Mapping Diagram
A mathematical sentence that shows the relationship between quantities that are not equivalent?
it is called an inequality
What is the meaning of zero correlation?
If variables have zero correlation, they do not have a linear relationship. Zero correlation shows that two things were not found to be related.
What is it called when one variable increases the other variable shows no relationship?
No correlation.
What is the difference between correlation and causality?
Correlation refers to a relationship between two variables where they change together, while causality indicates that one variable directly causes a change in another. In simpler terms, correlation shows a connection, while causality shows a cause-and-effect relationship.
When an experiment shows that two variable are closely related that experiment shows?
that there is a correlation between the two variables. However, correlation does not imply causation, so it is important to further investigate to determine the nature of the relationship between the variables.
What is the distinction between correlation and causation?
Correlation is a relationship between two variables where they change together, but it does not mean that one causes the other. Causation, on the other hand, implies that one variable directly influences the other. In simpler terms, correlation shows a connection, while causation shows a cause-and-effect relationship.
What is the correlation diagram showing the relationship between the variables in this dataset?
A correlation diagram visually represents the relationship between variables in a dataset. It shows how strongly and in what direction variables are related to each other.
When an experiment showes that two variable are closely related the experiment shows?
correlation
What shows relationship between implementation of programs and the sites ability to meet objectives and goals?
Trend correlation
If two variables are highly correlated the correlation coefficient will be at or near zero-true or false?
If two variables are highly correlated, the Pearson correlation will be close to -1.0 or +1.0. A correlation of zero shows no relationship.
What shows relationship between implementation of programs and the site's ability to meet objectives and goals?
D. Trend correlation
What is the difference between cause and effect vs correlation in research studies?
Cause and effect in research studies refer to a direct relationship where one variable causes a change in another variable. Correlation, on the other hand, indicates a relationship between two variables but does not imply causation. In simpler terms, cause and effect shows a clear cause-and-effect relationship, while correlation shows a connection between variables without proving one causes the other.
How is a scatter plot that shows no correlation different from a scatter plot that has a negative corrrelation?
A scatterplot with no correlation means that there is no relation between the two categories, a negative correlation means that the two categories have a relationship that as one gets greater the other gets smaller
