1+((A)/(2)-CF)× 1

The formula is:

$$\text{Median} = L + \left(\frac{\frac{N}{2} - CF}{F}\right) \times I$$

Here's what each variable represents:

• $L$: The lower boundary of the median class.
• $N$: The total number of observations (sum of all frequencies).
• $CF$: The cumulative frequency of the class preceding the median class.
• $F$: The frequency of the median class.
• $I$: The class width of the median class.

To use this formula, you would first need a frequency distribution table to identify the median class and the values for $L, N, CF, F,$ and $I$.
