Final answer:
Percentiles are used by paediatricians for growth tracking, in business to determine sales bonuses, and in academia for comparing SAT scores for university admissions.
Step-by-step explanation:
You would use percentiles in various contexts to compare individual values to a larger data set and understand the relative standing within that set. Some areas where percentiles are commonly used include:
- Paediatricians use percentiles to track a child's growth in terms of height and weight compared to other children of the same age.
- In business, they might determine sales bonuses by comparing an individual's sales figures against the entire sales team to decide the percentiles and reward performance accordingly.
- Universities and colleges often look at SAT scores in percentile terms to set a threshold for admissions. A school might require a score at or above the 75th percentile.
Thus, the answer to the question is that percentiles could usefully be applied in all these scenarios.
