For calculating the adjustment or adjustment factor, we need to follow two steps. First, we have to find the difference between the upper limit of one class and the lower limit of the class ahead. The second step is to divide the obtained value by 2. The value thus obtained is known as the adjustment factor which will be further deducted from the class limits and this is how we get actual class limits or true class limits. These are also known as class boundaries.
