MeanMedianMode

Mean, median, and mode
are introduced in this unit. Range and nonroutine 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 reallife 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. 
NonRoutine
Mean 
Students learn to
work backwards by solving nonroutine 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.
