    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!

    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?

      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.

      What resources are you after?

      @GP-eq3gh Před 5 lety

      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?

    • @ExamSolutions_Maths
      @ExamSolutions_Maths  Před 5 lety

      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.
