Is it always sometimes or never true that a scatter plot that shows a positive association suggests that the relationship is proportional?
It is sometimes true that a scatter plot showing a positive association suggests a proportional relationship, but not always. A positive association indicates that as one variable increases, the other tends to increase as well, but the relationship may not be linear or proportional. Proportional relationships require that the ratio of the two variables remains constant, which is not guaranteed by a positive association alone. Therefore, while some positively associated relationships can be proportional, others may not be.

What is numerical measure of linear association between two variables?
The numerical measure of linear association between two variables is typically represented by the Pearson correlation coefficient (r). This value ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 signifies no linear relationship. The closer the coefficient is to either -1 or 1, the stronger the linear association between the variables.
Must be positive the slope of an inverse relationship?
The slope of an inverse relationship
When a large number of cases are examined and a positive relationship is found what else should one expect to find?
a positive slope and a linear relationship
Is the difference of a negative integer and a positive integer is sometimes positive?
yes
What is linear position?
Positive Linear Relationships are is there is a relationship in the situation. In some equations they aren't linear, but other relationships are, that's a positive linear Relationship.
Which are the characteristics of proportional relationship graph?
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
Is the relationship between mass and inertia positive or negative?
The relationship between mass and inertia is positive. This means that as mass increases, inertia also increases. Inertia is the property of matter that resists changes in its motion, and it is directly proportional to mass according to Newton's first law of motion.
What does the sign of the correlation coefficient tell you about the association?
Positive correlation = positive association Negative correlation = negative association
How does a directly proportional graph look like?
In a directly proportional graph, the relationship between two variables is such that when one variable increases, the other variable also increases at a constant rate. This relationship is typically represented by a straight line that passes through the origin (0,0). The slope of this line is positive.
Is it possible for a scatter plot to have a positive or negative association that is not linear?
Certainly. It could, for example, be a power relationship such as y = x^3
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.
The purpose of branding is to do what?
create a positive associationCreate a positive association.
What is a positive linear relationship?
A linear relationship is one where your equation forms a straight line. A positive linear relationship is one where this line has a positive gradient.
What is positive linear relationship?
Positive Linear Relationships are is there is a relationship in the situation. In some equations they aren't linear, but other relationships are, that's a positive linear Relationship.
What is the magnitude of the electric field between two positive charges?
The magnitude of the electric field between two positive charges is directly proportional to the strength of the charges and inversely proportional to the square of the distance between them.
What is the best description of an association?
An association is a relationship between two or more variables where they co-occur or change together. It measures the strength and direction of the relationship between variables, indicating how one variable is affected by changes in another. Associations can be positive, negative, or neutral.
Fairy relationship with nature and animals?
Its a positive relationship
