Nice work! Here are some of the major takeaways about quantiles:

- Quantiles are values that split a dataset into groups of equal size.
- If you have
`n`

quantiles, the dataset will be split into`n+1`

groups of equal size. - The median is a quantile. It is the only 2-quantile. Half the data falls below the median and half falls above the median.
- Quartiles and percentiles are other common quantiles. Quartiles split the data into 4 groups while percentiles split the data into 100 groups.

### Instructions

To the right, we’ve shown three different histograms along with the deciles. Each histogram shows the SAT scores of the students that a *fake* university has accepted.

If you had an SAT score of `1350`

, which tenth of the data would you be in for each school? Which schools should you apply to? Would any of the schools be unrealistic options?
