Drawing boxplot from the following data, whiskers are determined from 1.5 IQR

1 | 0.026 | outlier |

2 | 0.048 | whisker low |

3 | 0.070 | Q1 |

4 | 0.072 | |

5 | 0.076 | Q2 |

6 | 0.084 | |

## Outlier

0.026 becomes **outlier** becauseĀ 1.5IQR boundary (IQR = Q3 – Q1 = 0.02908) for the lower boundary is Q1 -1.5IQR = 0.0404, hence whisker is 0.048 which is more close to the box inside making 0.026 outlier.
