- A straight line that best describes the distribution of points in a scatter plot is usually referred to as $\cdots$?

- A line of best fit can be used for the following except $\cdots$

- The average value of all the independent variables and the average value of all the dependent variables, when written
as an ordered pair $(a,b)$ is known as $\cdots$?

- Which of the following can be considered a mathematical model?

- Find the mean coordinate for the points: $(0,0),(2,1),(3,3),(-2,3),(5,2)$.

- Find the mean coordinate for the points: $(-1,-1),(0,0),(2,1),(3,3),(-2,3),(4,6)$

- The general direction that a set of data takes is known as $\cdots$

- When the depedent variable increases as the independent variable increases, the correlation type is $\cdots$

- When the dependent variable decreases as the independent variable increases, the correlation type is $\cdots$

- When there is no discernible pattern in a data set, the corresponding correlation is $\cdots$?
