I just gave my first quiz in Canvas and I included a formula question where students were given 6 randomly-generated numbers and were asked to calculate the mean. I put the following formula into Canvas for the solution:
Every single one of my students was marked incorrect on this question because Canvas did the math wrong. After the fact I tried using mean(a,b,c,d,e,f) and that gave the same incorrect answer.
Any ideas what is going on??
