The upper part of the left or right page of a field book must contain 9 items, including: | project name, location, date, time of day, starting/finishing time, weather, party, instrument type, instrument number |

What type of field notes are taken at the time of observations? | Original field notes |

If field notes are copied they must be marked as? | copied |

What should you do if a partial or entire page of field notes needs to be deleted? | diagonal lines should be drawn through opposite corner and void should be written across the page |

What is not permitted in handwritten field notes? | erasing |

What are the 5 general requirements of handwritten field notes? | accuracy, integrity, legibility, arrangement, clarity |

How should a number be rounded if the digit to be dropped is greater than 5? | the number is written with the preceding digit increased by one |

How should a number be rounded if the digit to be dropped is exactly 5? | the nearest even number is used for the preceding digit |

How should a number be rounded if the digit to be dropped is lower than 5? | the number is written without the digit |

How many significant figures should be in the result of a multiplication or division problem? | the number of significant figures in the answer is equal to the least number of significant figures in any of the factors |

What is the first step in determining the number of significant figures when adding and subtracting? | identify the rightmost significant digit in each number |

True or False, when measurements need to be converted, significant figures are determined after expressing the measured value in its smallest units? | True |

True or False, a conversion constant effects the number of significant figures represented in a result? | False, it does not effect the number of significant figure in the result |

True or False, you may need to provide a higher number of significant figures in a result even though it isn't required by the rules of significant figures? | True |

True or False, in intermediate calculations carry one more digit than required? | True |

True or False, zeros at the end of an integral value may or may not be significant? | True |

Raw Data File | original unreduced measurements and cannot be altered in the field |

Coordinate File | computed coordinate values generated using the observations and any applied field corrections |

Significant Figures | the number of significant figures in any observed value includes the positive (certain) digits plus one (only one) digit that is estimated or rounded off and therefore questionable |
