i remember my teacher was saying something like whenever we have to tabulate students marks we use only inclusive class interval (or i doubt it could be exclusive) or something like when decimal numbers like 3.5 are there we use something (that is either inclusive or exclusive) but i dont remember all that now

so i want to know when should i show certain data (of rainfall, students marks, population etc.) in a inclusive method and exclusive method

like i guess when marks of a students are given she told us to use only inclusive class interval but not sure
