campbell_st · Answer

this is quantitative data... so you can exclude the mode

you need to decide if the data contains outliers

it it does contain outliers, the median is the best measure

if you think the data is compact... then use the mean

In you conclusion you many like to suggest that Mr Tham show the class how to study smarter, rather than harder...
