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.
