What does the a and b represent

[@tullamaths]

The a and b are used when forming "the line of best fit" in statistics (equation of the line).

[@gillgill334]

[@tullamaths]

Is it possible to find R on this calcukator if I'm only given the sigma of X, Y, XY, X2 & Y2 in the question rather than a list of data points for X & Y?

[@Thelegend-fm2tt]

Absolutely not

[@ghinashawi6842]

What do u do if u don’t have the OPIN button

[@tullamaths]

My video is based on the new Casio calculator. If using old Casio you need to select Shift followed by 1

[@KimSeokjin-np7zw]

what do the a and b mean please?

[@tullamaths]

The a and b are used when finding "The Line of Best Fit". The a stands for the y-intercept and the b is the slope when forming the equation of the line.
