  • 1

    What is a Line of Best Fit

    A linear line that tries to approximate the relationship between two variables by getting near as many data points as possible

  • 2

    What is the "Least Squares Regression Line"

    A line of best fit that minimises the sum of the squares of the distances of each data point from the line

  • 3

    What is the Equation for the Regression line (line of best fit) of y on x

    y = a + bx, where a and b are constants

  • 4

    What do the Values a and b on a Regression line represent

    a is the intercept (y value at x = 0), b is the gradient (change in y for a change in x of 1)

  • 5

    b is positive if

    The data is positively correlated

  • 6

    b is negative if

    The data is negatively correlated

  • 7

    When can a Rgeression Line be used

    When there is a linear relationship between two variables

  • 8

    When is a Regression Line most reliable for predicting values

    When the value for the dependent variable is within the given range of data

  • 9

    What is Interpolation

    Predicting values within the given range of data

  • 10

    What is Extrapolation

    Predicting Values outside the given range of data
