Description |

Range | To find the range of a set of data. Whole numbers, integers, and decimals are used in the problems presented. All problems are drawn from real-life situations. |

Arithmetic Mean | To define and compute the arithmetic mean. Whole numbers and decimals are used throughout. Rounding to a particular decimal place is required. |

Non-Routine Mean | Students learn to work backwards by solving non-routine mean problems. For example, finding the missing number given the mean and the other numbers in the set. Whole numbers and decimals are used throughout. |

Median | To find the median of a set of data. Sets with an odd and with an even number of items are explored. Whole numbers and decimals are used throughout. |

Mode | To find the mode of a set of data. Bimodal sets are also?covered. A distinction is made between a set with no mode and one with a mode of zero. Whole numbers, signed numbers, and decimals are used in the problems. |
