Understanding Linear Regression

Finding the median of data

Fitting a line or curve to data

Determining the mode of data

Calculating the mean of data

It describes a linear relationship

It is used to calculate the mean

It is used to find the median

It represents a quadratic equation

Three median method

By eye

Quadratic regression

Least squares regression line

Least squares regression line

By eye

Three median method

Polynomial regression

Ensuring all points are above the line

Balancing the number of points above and below the line

Maximizing the distance from the line to the points

Minimizing the number of points on the line

By finding the average of y-coordinates

By using the rise over run method

By subtracting the smallest x-coordinate from the largest

By calculating the sum of x-coordinates

The highest point on the line

The point where the line crosses the y-axis

The point where the line crosses the x-axis

The lowest point on the line

The line is horizontal

The line is vertical

The line slopes upwards

The line slopes downwards

y = -x/12 + C

y = x/12 + C

y = 12x + C

y = -12x + C
