What is a relationship between two variables in witch the data do not increase or decrease together at the same rate?
A relationship between two variables in which the data do not increase or decrease together at the same rate is known as a non-linear relationship. In this type of relationship, the rate of change between the variables can vary, leading to a situation where one variable may change significantly while the other changes little, or vice versa. This can often be represented by a curve rather than a straight line on a graph. Non-linear relationships are common in many real-world scenarios, such as in economics or Biology.
What else can I help you with?
What is the relationship between two quantites that increase or decrease together called?
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
What fo you call direct relationship in which two factors increase or decrease together?
A direct relationship in which two factors increase or decrease together is called a positive correlation. In this scenario, as one variable rises, the other variable also rises, and similarly, if one falls, the other falls as well. This relationship is often represented graphically with an upward-sloping line.
What does a positive or negative correlation mean?
A positive correlation indicates that as one variable increases, the other variable also tends to increase, suggesting a direct relationship between the two. Conversely, a negative correlation means that as one variable increases, the other tends to decrease, indicating an inverse relationship. Correlation does not imply causation; it simply reflects the degree to which the two variables move together.
When one variable increases and there is an increase in another or one variable decreases and there is a decrease in another there is?
a positive correlation between the two variables. This means that as one variable changes in a particular direction (either increasing or decreasing), the other variable tends to change in the same direction. Positive correlations suggest a direct relationship, where the variables move together, indicating potential interdependence or similar underlying factors influencing both.
What does it mean when a correlation exists between two variables?
When a correlation exists between two variables, it indicates that there is a statistical relationship between them, meaning that changes in one variable are associated with changes in the other. This relationship can be positive (both variables increase together) or negative (one variable increases while the other decreases). However, correlation does not imply causation; it does not mean that one variable causes the change in the other. Correlation can arise due to various factors, including chance, confounding variables, or a direct causal relationship.
When two variables increase or decrease together in the same ratio they?
Are in direct proportion
What does a correlation coefficient of 0.8 mean?
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
What is the implication of any correlation found between the variables?
Correlation is a measure of the degree to which two variables change together. Positive correlation means that the variables increase together and decrease together. Negative correlation means that one variable increases when the other decreases.Correlation does not imply causality.Correlation is a measure of the degree to which two variables change together.

What is the relationship between two quantities that increase or decrease together?
Direct variation
What is the relationship between two data sets when their data values increase or decrease together?
It is a positive relationship.
What does a positive correlation between variables x and y imply?
It implies that an increase in x is accompanied by an increase in y. And similarly, they decrease together.
What is the relationship between two quantites that increase or decrease together called?
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
The relationship between two quantites that increase or decrease together is called?
Variation in direct proportion.
The relationship between two quantities that increase or decrease together is called what?
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
The relationship between two quantities that increase or decrease together is called?
direct variation or positive correlation.
What does it mean if two variables have a positive correlation?
If the correlation is positive, as one increases so does the other.
What does the value of a correlation coefficent reflects?
A correlation reflects the strength of the relationship between two variables. A correlation doesn't reflect causation, but merely that two phenomena are present at the same time. The closer the value is to 1, the stronger the relationship between two variables is. This value can be positive or negative. A negative value merely indicates that, as the values on one variable increase, the values on the second variable decrease. A positive correlation indicates that both values will increase or decrease together.
