Thank you, your videos are very clear and you include all the potential variants of how a question could be presented, instead of just one specific example!
Did you check out 13:06 ? One tail if it is > or < , two tail if it is not equal to. The question will generally ask you to test one or the other but if not you should be able to tell based on the question if the product moment for testing is a positive or negative value.
Only what you currently see on the website, under the vectors section. They link back to old papers. There is not much yet available for the new spec as there has not been many exams.

Quick Question, how do you know when to do a two-tailed test and a 1 tail-test? Will the exam question be specific and tell us to do a two-tail test?

ExamSolutions meant to say “where” but for the new spec where can i get questions for vectors? Apart from the specimen papers are there anymore?

How do you calculate PMCC? Or will it be given every time?
You can see it here www.examsolutions.net/tutorials/measuring-linear-correlation/?level=A-Level&board=Edexcel&module=Statistics%20A-Level&topic=1844
It should be given normally
How do you know wheter there is enough evidence or not?
