What else can I help you with?
In a coordinate graph of two related variables when does it make sense to connect the points?
When the data on the graph is continuous,it does make sense to connect the points on the graph of 2 related variables.
What can you say about the correlation coefficient and the correlation description of the correlation when the points lie exactly on either vertical line or horizontal line?
The observed relationship indicates that the a one-to-one correspondence exists between the variables of interest. In effect, the value of the obtained r-value is -1 or 1.
Find the distance between the points (4 3) and (0 3).?
The distance between the points of (4, 3) and (0, 3) is 4 units
What is a solution of a linear equation in two variables?
The solution of a linear equation in two variable comprises the coordinates of all points on the straight line represented by the equation.
If you know two points on a line how can you find the rate of change of the variables being graphed?
You divide the difference in y-coordinates by the difference in x-coordinates. Or whatever the variables are.
Fill in the blank When the data points on a graph are scattered with no clear pattern there is between the two variables?
no correalation
What happens when two variables are unrelated on a graph?
You get a set of points that appear to be scattered randomly.
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.
In a coordinate graph of two related variables when does it make sense to connect the points?
When the data on the graph is continuous,it does make sense to connect the points on the graph of 2 related variables.
What is the relationship between two variables?
The relationship between two variables is called a relation. A relation in which a set of input values maps onto a set of output values such that each input corresponds to at most one output is called a "function." Functions do not necessarily have to be lines; they do not even have to be exponential, or parabolic, or continuous. A bunch of scattered points or lines that meets the requirements can still be considered a function involving two variables.
The function N gives a relationship between the variables Player and Points?
"Player" is the independent variable, and "Points" is the dependent variable.
What is linear pattern?
A linear pattern is a consistent and predictable change in a series of data points that can be represented by a straight line on a graph. It indicates a constant rate of change between the variables being studied.
When the data points on a graph tend to go up as they go to the right there is between the two variables?
Positive correlation
What two variables do you need to know to determine the gradient between two points on a map?
The height of the land, and the scale of the map
What is collinearity?
It means that a certain set of points are all on the same line.
Is it possible to make a prediction based in a scatter plot with no correlation?
Correlation is an estimate of a linear relationship between two variables and takes no account of non-linear relationship. If the relationship is quadratic and the domain is symmetric about some point, the correlation will be zero. It is, thus possible for the points on the scatter plot to lie exactly on a parabola while the calculated correlation is zero. In such a case, it is easy to make a prediction despite no correlation.
A best line fit may not be very useful between these two variables since the data points on the graph are?
Not linearly related.
