whole numbersNumbers that do not contain decimals or fractions IntegersWhole numbers and their opposites rational numbersAll positive and negative integers, fractions and decimal numbers.Real numbersAny number that can be placed on a number line.Including numbers that do not end, and number like pi A SetA collection of numbers DiscreteValues that are distinct, separate and unconnected ContinuousValues in a set that are connected, without gaps Quantitative DataConsists of data values that are numerical, representing qualities that can be counted or measured Categorical dataAlso called qualitative data. Consists of data that are groups, such as names or labels, and are not necessarily numerical.Graphical displaysVisual displays of data sets data setAny collection of numeric values, such as measurements, observations, or survey responses DistributionAn arrangement of values that illustrates their frequency or occurrence

Pie chartA graphical display that shows data in categories as percentages of a circle Bar chartA graph that displays data that is distributed over groups or categories Relative frequencyA way to approximate a percentage by dividing the number of times an event occurred in an experiment by the total number of trials.frequency distributionA record of the number of times data occurs within a certain category Dot plotA graphical representation of data that plots the frequency of data along a horizontal line OutliersAn observation point (number) that is significantly distant from the other observations in the dataset Stem plotsA visual representation of data in which individuals data points are plotted to the right of a horizontal line, or chart, and the left (the "stem") shows the interval categories Box plotA graphical rendering of the range and the first and third quartiles of a data set with the data set's median in between Measure of central tendency A summary measure that is used to describe an entire set of data with one value that represents the middle or center of the data sets distribution. There

are 3 main measures: mean, median or mode

HistogramA graph that displays data through vertical bars that show the counts or numbers in each range ShapeThe outline of a set of data displayed on the coordinate axes ScaleThe relationship between units and their visual representation on a graph Check sheetA structured form or table that allows data to be collected by marking how often an event has occurred in a certain interval Guides for histogram< 50>250 divide into 10-20 intervals SymmetryThe quality of the data having the same shape on both sides of the mean Normal distributionA comment type of distribution of data points that for a a bell shaped, symmetrical curve around the mean Skewed distributionA distribution that is not symmetrical but has a greater quantity of data on one side of the mean SkewnessA measure of the degree to which a probability distribution "leans" toward one side of the average, where the median and mean are not the same
