which of the following is not an advantage of tubular presentation of data?

The option that is not an advantage of tubular presentation of data is "occupy more space than mathematical equations". Tubular presentation of data is a way of presenting data in rows and columns, much like a table. It has several advantages, including enabling easy location of required figures, making for easy comparison of figures, and showing whether the figures are increasing or decreasing. However, the disadvantage of tubular presentation of data is that it may occupy more space than mathematical equations, making it less efficient in some cases where space is limited or when a lot of data needs to be presented in a small area. Therefore, the correct option is "occupy more space than mathematical equations".
