### 2. Direct Measurement

To demonstrate, determine the MPV of the following set of distance measurements:

262.35 |

262.40 |

262.33 |

262.31 |

262.38 |

To define the function, set up Equation C-3 for each measurement and add them together:

Take the first derivative of the function, set it equal to zero, and solve for the MPV:

Note that the MPV is the simple average of the observation set.
