Visualizing Data Key terms • bell curveIn mathematics, the bell-shaped curve that is typical of the normal distribution. • box plotA graphical summary of a numerical data sample through five statistics: median, lower quartile, upper quartile, and some indication of more extreme upper and lower values. • breedingthe process through which propagation, growth, or development occurs • continuous variablea variable that has a continuous distribution function, such as temperature • controla separate group or subject in an experiment against which the results are compared where the primary variable is low or nonexistence • correlationOne of the several measures of the linear statistical relationship between two random variables, indicating both the strength and direction of the relationship. • cross tabulationa presentation of data in a tabular form to aid in identifying a relationship between variables • densitythe probability that an event will occur, as a function of some observed variable • discrete variablea variable that takes values from a finite or countable set, such as the number of legs of an animal • evolutiona gradual directional change, especially one leading to a more advanced or complex form; growth; development • frequencynumber of times an event occurred in an experiment (absolute frequency) • gradientof a function y = f(x) or the graph of such a function, the rate of change of y with respect to x, that is, the amount by which y changes for a certain (often unit) change in x Free to share, print, make copies and changes.

Visualizing Data • graphA diagram displaying data; in particular one showing the relationship between two or more quantities, measurements or indicative numbers that may or may not have a specific mathematical formula relating them to each other. • histograma representation of tabulated frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area equal to the frequency of the observations in the interval • histograma representation of tabulated frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area equal to the frequency of the observations in the interval • histograma representation of tabulated frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area equal to the frequency of the observations in the interval • histograma representation of tabulated frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area equal to the frequency of the observations in the interval • interceptthe coordinate of the point at which a curve intersects an axis • interquartile rangeThe difference between the first and third quartiles; a robust measure of sample dispersion. • linea path through two or more points (compare ‘segment'); a continuous mark, including as made by a pen; any path, curved or straight • linear regressionan approach to modeling the relationship between a scalar dependent variable and one or more explanatory variables denoted . • outliera value in a statistical sample which does not fit a pattern that describes most other data points; specifically, a value that lies 1.5 IQR beyond the upper or lower quartile • plota graph or diagram drawn by hand or produced by a mechanical or electronic device • probability distributionA function of a discrete random variable yielding the probability that the variable will have a given value.
