13 | 0.787399 |

14 | 1.209767 |

15 | 1.414172 |

16 | 1.718419 |

Tabulate the data generates the following stats:

Min | -2.53802 |

Mean | 0.097223 |

Quantiles50 | 0.140362 |

Quantiles95 | 1.718419 |

Max | 1.718419 |

Std Dev | 1.023793 |

I am curious to know how JMP derives 95 percentile or for any random percentile.

Thanks!
