3. Percentile refers to the 99 values that split the population data into 100 equal fragments such that each fragment is representative of 1/100th of the population.

4. Percentile rank is a quantitative process of dividing a set of data into 100 equal parts. For this purpose, it is necessary to arrange the data systematically in ascending order.

5. Mendenhall and Sincich Method ROUND UP ROUND DOWN
