What trend line means?
The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight.

What does the intersection of the two lines of best fit tell us about the relationship between the variables in the data set?
The intersection of the two lines of best fit in a data set indicates the point where the predicted values of the variables are equal. This suggests that there is a common value or relationship between the variables at that specific point.
What is the best way to represent data that compares the relationship between two variables?
A scatter plot.
What is something that uses bars to show the relationship between two variables?
A bar graph form the best, ME!
Is the regression equation a mathematical equation that defines the relationship between two variables?
No. It is an estimated equation that defines the best linear relationship between two variables (or their transforms). If the two variables, x and y were the coordinates of a circle, for example, any method for calculating the regression equation would fail hopelessly.
What conclusions can you draw if the line of best fitting on a linear graph does not slope either up or down but is horizontal?
The conclusion would be that there is no evidence of a linear relationship between the variables. There could well be a non-linear (eg quadratic) relationship.
What are the advantages and disadvantages of DIAGRAMMING?
ADVANTAGES Shows relationship between two variables best method to illustrate a non-linear pattern.
What is regression line?
Regression techniques are used to find the best relationship between two or more variables. Here, best is defined according to some statistical criteria. The regression line is the straight line or curve based on this relationship. The relationship need not be a straight line - it could be a curve. For example, the regression between many common variables in physics will follow the "inverse square law".
What are the advantages and disadvantages of scatter diagram?
ADVANTAGES Shows relationship between two variables best method to illustrate a non-linear pattern.
What statements best describe a conversion factor?
Given two variables n a linear relationship, the conversion factor between them is the gradient of their graph.
Which graph BEST represents the relationship between mass and inertia?
A scatter plot with mass on the x-axis and inertia on the y-axis is the best graph to represent the relationship between mass and inertia since it allows for visualizing any potential correlation or pattern between the two variables.
What is A line drawn in the midst of the points on a scatter plot in an attempt to estimate the mathematical relationship between the variables of the plot?
It is called the line of best fit
