Calculator Work – Correlation Coefficient

Trying to include a little more detail in the solutions regarding calculator work. This slide is from the recent LCOL P2 and shows how to use a CASIO calculator to find the standard deviation of a set of data.

As the year goes on I’ll retrospectively go through the older Statistics question and solution packs and amend them…
The new website is live if any members want to DM for a password.

A few little things still to do (didn’t realise there would be so much work involved!!) before it signed off on!
I’ll be adding in amended versions of all of the question and solution packs to include the 2022 papers later in the week too.
