Mean, median, and mode are introduced in this unit. Range and non-routine mean problems are also covered. Examples include problems with whole numbers, decimals and integers. Try our sample lessons below, or browse other units of instruction.

Topics |
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. |

Practice Exercises | To complete 10 additional exercises as practice. To assess students' understanding of all concepts. |

Challenge Exercises | To solve 10 additional problems that challenge students' understanding of all topics covered. Problems are drawn from real-life situations. To hone students' problem-solving skills. |

Solutions | To review complete solutions to all exercises presented in this unit. Includes the problem, step-by-step solutions, final answer and units for each exercise. |

Learning Objectives | Learn About Statistics Including Range, Mean, Median And Mode. Data Sets That Are Bimodal, Have No Mode, And With An Even Or An Odd Number Of Data. |
