To find the mean deviation about the median of the given frequency distribution, we will follow these steps: ### Step 1: Create a Frequency Distribution Table We will first list the classes, their mid-values (x_i), frequencies (f_i), and cumulative frequencies (CF). | Class | Mid-value (x_i) | Frequency (f_i) | Cumulative Frequency (CF) | |----------|------------------|-----------------|---------------------------| | 0 - 6 | 3 | 8 | 8 | ...
