@PinoyMathematician
@PinoyMathematician 3 года назад
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

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
@PinoyMathematician
@PinoyMathematician 2 года назад
You have to subtract. It is not lower class boundary if you dont subtract .5, it is only lower limit.
