    For student four there is an obvious anomalous result that must be excluded when calculating the mean so only divide by four

    I think the answer is just 3, add all the numbers up for each row and divide the answer by 5 for each of them

    Well if you start looking at anomalous results, 2, 3 and 4 would all be correct means... Strange that there is no option for 2, 3 and 4.

    I think is has something to do with the significance level, as you can't be more accurate than the data you have. but i'm not sure.

    Not 100% but I think why they didn't put 4 is because it has a decimal point.You can't have half a bubble and our teacher always tells us our results and mean has to be to the same precision so for the mean of student 4 to be correct they would need to round it.

    That would make sense actually
