IB: Trasketball
Y’all have a quiz on Monday.
Below is the least squares regression. Reduce it down to the “y = mx +b” form.
Below is the least squares regression. Reduce it down to the “y = mx +b” form.
Below is the least squares regression. Reduce it down to the “y = mx +b” form.
Below is the least squares regression. Reduce it down to the “y = mx +b” form.
Find the Least Squares Regression line
Given the following data:
Sx =4.59
Sy =2.54
Sxy = 0.955
= 10.3 = 12.7
Find the Least Squares Regression line
Given the following table:
Find the Least Squares Regression line
Given the following data:
Sx = 13.6
Sy = 19.3
Sxy = 9.54
= 112 = 254
Find the Least Squares Regression line
Given the following table:
Given the line, make a prediction for the y-value:
The Least Squares Regression:
X = 13.9
Given the line, make a prediction for the y-value:
Y = mx + b:
y = 25.7x – 14.3
X = 4.2
Given the line, make a prediction for the y-value:
The Least Squares Regression:
X = 5.44
Given the line, make a prediction for the y-value:
Y = mx + b:
y = 32x + (-12.8)
X = (-2.7)
