 /**
- * QuartileBound.
+ * A record representing the quartile bounds of a dataset.
+ * <p>
+ * This class encapsulates the lower and upper bounds of a dataset, which are typically used for detecting outliers in
+ * the data. The bounds are calculated based on the interquartile range (IQR) of the dataset. Values below the lower
+ * bound or above the upper bound may be considered outliers.
+ * <p>
+ * Quartile bounds consist of:
+ * <ul>
+ *   <li>{@code lowerBound} - The lower bound of the dataset, typically {@code Q1 - 1.5 * IQR}.</li>
+ *   <li>{@code upperBound} - The upper bound of the dataset, typically {@code Q3 + 1.5 * IQR}.</li>
+ * </ul>
+ * </p>
+ * <p>
+ * Example usage:
+ * <pre>
+ * QuartileBounds bounds = QuartileBounds.builder()
+ *     .lowerBound(1.5)
+ *     .upperBound(7.5)
+ *     .build();
+ * </pre>
  *
- * @param upperBound
