## WitCH 140: Honey, Don’t

We’re snowed with grading essays for the Evil Mathologer, and we’re trying very hard to get to a few larger posts. But for now, a quick WitCH. We don’t pay much attention to Foundation Mathematics, which is supposed to be the Easier Than Easy Maths Subject. Commenter Ron, however, emailed us about the following question on VCAA’s sample exam, posted last year. (See also this post.)

## One FEL Swoop: The Foundation Error List

This is the (new) newly established home for Foundation Mathematics exam errors. The guidelines are given on the Methods error post, and there is also a Specialist error post, and a (now renamed) General error post (with unchanged link).  As with General Maths, I will not look much at the Foundation exams, only posting errors as they are brought to my attention.

2023 Exam (No exam yet, discussed here)

MCQ13 The key to the graph is confusing, and wrong. Some indication that “payment” and “interest” are cumulative had to be included.

Q1(c) There are two methods of working out the percentage increase, which give different answers. One method is unlikely to have been considered by students, but this still should not occur.

Q2(e) The question makes zero sense, since it assumes that a person cannot play both a ball sport and a non-ball sport. The question also fails to specify the percentage is of females participating in a sport.

Q6 An awfully written question, throughout confusing usage with market share. There is probably only one plausible way to answer the questions, but this is teaching Not Maths.

Q6(a) The 2022 percentages in the graph do not total to 100%. This in itself is ok, but it leads to two potential answers to (a); one answer is unlikely to be given, but this still should not occur. The graph should have been appropriately labelled.

Q11 The outer rectangle on the diagram doesn’t mean anything and was probably actively confusing.
