When taking the lower class boundary for median or mode are we supposed to subtract .5 from the lower class boundary or just you take that lower class boundary as itself without subrtracing .5

For constructing frequency table, usually the class size is given in the instruction. But if it's not given, then you use the formula i = Range / k where k = 1 + 3.322logN
