cit.4Adapted from WisconsinDepartment of Public Instruction,op.cit.Expanded form.A multi-digit number is expressedin expanded form when it iswritten as a sum of single-digit multiples of powers often. For example,643 = 600 + 40 + 3.Expected value.For arandom variable, theweighted average of itspossible values, withweights given by theirrespective probabilities.First quartile.For a dataset with median M, the firstquartile is the median ofthe data values less thanM. Example: For the dataset {1, 3, 6, 7, 10, 12, 14,15, 22, 120}, the firstquartile is 6.2See also:median, third quartile,interquartile range.Fluency.The ability to useefficient, accurate, andflexible methods forcomputing. Fluency doesnot imply timed tests.Fluently.See also:fluency.Fraction.A numberexpressible in the forma/bwhereais a whole numberandbis a positive wholenumber. (The word fractionin these standards alwaysrefers to a non-negativenumber.)See also:rationalnumber.Identity property of 0.See Table 3, page 96.Independently combinedprobability models.Twoprobability models are saidto be combinedindependently if theprobability of each orderedpair in the combined modelequals the product of theoriginal probabilities of thetwo individual outcomes inthe ordered pair.Integer.A numberexpressible in the formaorafor some wholenumbera.Interquartile Range.Ameasure of variation in aset of numerical data, theinterquartile range is thedistance between the firstand third quartiles of thedata set. Example: For thedata set {1, 3, 6, 7, 10, 12,14, 15, 22, 120}, theinterquartile range is156 = 9.See also:firstquartile, third quartile.Justify:To provide aconvincing argument forthe truth of a statement to aparticular audience.Line plot.A method ofvisually displaying adistribution of data valueswhere each data value isshown as a dot or markabove a number line. Alsoknown as a dot plot.3Mean.A measure of centerin a set of numerical data,computed by adding thevalues in a list and thendividing by the number ofvalues in the list. (To bemore precise, this definesthe arithmetic mean)Example: For the data set{1, 3, 6, 7, 10, 12, 14, 15,22, 120}, the mean is 21.Mean absolute deviation.A measure of variation in aset of numerical data,computed by adding thedistances between eachdata value and the mean,then dividing by thenumber of data values.Example: For the data set{2, 3, 6, 7, 10, 12, 14, 15,22, 120}, the meanabsolute deviation is 20.
OHIO’S LEARNING STANDARDS| Mathematics | 201792__________________________________Median.A measure ofcenter in a set of numericaldata. The median of a listof values is the valueappearing at the center of asorted version of the list—or the mean of the twocentral values, if the listcontains an even numberof values. Example: For thedata set {2, 3, 6, 7, 10, 12,14, 15, 22, 90}, the medianis 11.
