Statistics and Mechanics Revision Sheet | Edexcel Maths A-Level 2023

[@polVallverdu-mf9uk]

at 6:36, why is extrapolation defined as making predictions outside the data range "incorrectly"? I thought it was just the act of making said predictions

[@MrAstburyMaths]

Yes good point, I should have used the word "unreliably" rather than "incorrectly". I have updated the sheet to reflect this. Thank you

the pure papers were so helpful. Is it possible to get a predicted paper for paper 3?

[@MrAstburyMaths]

Hi, I’ll be posting as many applied papers as possible. There are so few topics that all papers are predicted papers! I recommend doing as many past papers as possible

[@F16Fighter]

sum of x squares
does this mean you add up all the xs, and then square them, or does it mean you square each value of x, then add them?

[@dasvidanya2694]

Square them all, then add them 😁 good luck with the exam!

Why is median at 18 for interpolation between 16 and 21

[@MrAstburyMaths]

It’s was just an example I made up! In this example there must have been 35 data points. Therefore the median would be in the 18th position and then you use interpolation to find the value of the median.
