One variable is a multiple of the other. One context would be the cost of buying tins of baked beans - with no discount for large purchases. In the cost of one tin is x units then the cost of b tins will by b*x units.

How does the pattern of change between two variables ina linear relationship show up in A contextual situation?
The answer requires the relevant context to be given.
How does the pattern of a change for a linear relationship show up in a table graph and an equation of the relationship?
you put in what x is and solve it for y! thats the answer!
What is the word for a guess about a pattern or relationship based on observations?
This would be called a hypothesis.
How will you interpret the coefficient of correlation?
Correlation is a measure of the strength of a linear relationship between two variables. In theory it ranges between -1 and +1, although in practice, random and observation error make this value smaller.Near -1, the correlation is very strongly negative, which means that an increase in one variable is accompanied by a decrease in the other.Near +1, the correlation is very strongly positive, which means that an increase in one variable is accompanied by an increase in the other.Near 0, the correlation is weak and there is no linear pattern in which the two variables change.There are two very critical points to remember:Correlation does not measure causation. For example, the number of cars on the road is correlated to my age but my getting older does not cause more cars to be made and cars do not cause me to grow old (at least, not with most drivers!)Correlation will only measure a linear relationship. If you examine a relationship like y = x2, over a symmetric interval, the correlation coefficient will be close to 0. But there is, clearly, a very strong relationship - just that it is not linear.Finally, the importance of any correlation coefficient is subjective and depends on the context. A correlation coefficient that is high for a sociological study may be considered moderate for a high school physics experiment.
Ann recorded the effects of watching television on physical fitness. Which of these is a response variable?
Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables.Variable - not consistent or having a fixed pattern; liable to changePhysical fitness

What are the advantages and disadvantages of DIAGRAMMING?
ADVANTAGES Shows relationship between two variables best method to illustrate a non-linear pattern.
What are the advantages and disadvantages of scatter diagram?
ADVANTAGES Shows relationship between two variables best method to illustrate a non-linear pattern.
A general pattern of a scatter plot?
There is no such thing as a general pattern. Depending on the variables and the relationship between them, you can have points all over the plot, exactly on a straight line or a curve, or close to such a line or curve.
What is the relationship between spatial process and spatial pattern?
there is a reciprocal relationship between the spatial pattern and the spatial process.
What the relationship between spatial pattern and spatial process?
there is a reciprocal relationship between the spatial pattern and the spatial process.
When the data points on a graph are scattered with no clear pattern there is between the two variables?
No correlation. Answer provided by

no correalation
What is the meaning of correlation coefficient?
The correlation coefficient takes on values ranging between +1 and -1. The following points are the accepted guidelines for interpreting the correlation coefficient:0 indicates no linear relationship.+1 indicates a perfect positive linear relationship: as one variable increases in its values, the other variable also increases in its values via an exact linear rule.-1 indicates a perfect negative linear relationship: as one variable increases in its values, the other variable decreases in its values via an exact linear rule.Values between 0 and 0.3 (0 and -0.3) indicate a weak positive (negative) linear relationship via a shaky linear rule.Values between 0.3 and 0.7 (0.3 and -0.7) indicate a moderate positive (negative) linear relationship via a fuzzy-firm linear rule.Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship via a firm linear rule.The value of r squared is typically taken as "the percent of variation in one variable explained by the other variable," or "the percent of variation shared between the two variables."Linearity Assumption. The correlation coefficient requires that the underlying relationship between the two variables under consideration is linear. If the relationship is known to be linear, or the observed pattern between the two variables appears to be linear, then the correlation coefficient provides a reliable measure of the strength of the linear relationship. If the relationship is known to be nonlinear, or the observed pattern appears to be nonlinear, then the correlation coefficient is not useful, or at least questionable.
What is a cyclic relationship?
Something that is cyclic repeats a pattern of some sort. A cyclic relationship is a relationship between two people or things that repeat a pattern. For example: 1. Breathing is a scientific cyclic relationship where the oxygen cycles into the body and carbon dioxide is released in a periodic pattern. 2. The relationship between your two friends who continuously break up and get back together many times could be considered a cyclic romance/relationship.
What is the pattern between the diameter and radius?
By pattern, I'm assuming you mean relationship. The radius is half the length of the diameter.
What is a scatter plot and what kind of relationship does it show?
a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present. Scatter plots are similar to line graphs in that they use horizontal and vertical axes to plot data points. However, they have a very specific purpose. Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation .
