| The terms tercile, quartile, quintile and decile should refer to the percentiles which divide the distribution into 3, 4, 5, or 10 equal parts, respectively. |
| Comparison of population percentiles requires an adequate amount of data for statistical significance. |
| Descriptive statistics include frequency distributions and percentiles, mean, standard deviation, range of scores, skewness, and kurtosis. |
| Bars above histograms indicate the 1st, 5th, 95th, and 99th percentiles of the cumulative frequency distribution. |
| This is refected in the similar values across the percentiles of exposure. |
| Table 1, which contains the simulation results, therefore displays percentiles of this distribution. |
