Fractions, Decimals, Percents, and Using Data

TermDefinition
bar graph a graph with horizontal or vertical bars that represent data
denominator the "downstairs" number in a fraction that describes the number of equal parts in the whole
numerator the "upstairs" number in a fraction that describes the number of parts of the whole being considered
equivalent fractions fractions with different denominators that name the same amount
improper fraction a fraction with a numerator that is greater than or equal to its denominator
mixed number a number that is written using both a whole number and a fraction
circle or pie graph a graph in which a circle and its interior are divided into sectors corresponding to parts of a set of data
percent per hundred; out of a hundred
percent circle a tool that is used to measure and draw figures that involve percents, such as circle graphs
fraction stick a diagram used to represent simple fractions
rounding, round to the nearest... to approximate a number to make it easier to work with or to check for precision
repeating decimal a decimal in which one digit or a group of digits is repeated without end
sector a region bounded by, and including, an arc and two radii or a circle; also called a wedge
unit fraction a fraction whose numerator is 1
unit whole an entire object, collection of objects, or quantity being considered in a problem
common denominator a nonzero number that is a multiple of the denominators of two omr more fractions
contour map a map that uses contour lines to indicate areas having a particular feature, such as elevation or climate
contour line a curve on a map through places where a measurement is the same
line plot a sketch of data in which checkmarks, Xs, or other symbols above a labeled line show the frequency of each value
cubit an ancient unit of length, measured from the point of the elbow to the end of the middle finger
fair game an equal chance of winning or losing
fathom a unit of length equal to 6 feet, or 2 yards
frequency table a table in which data are tallied and organized
frequency graph a graph showing how often each value occurs in a data set
great span the distance from the tip of the thumb to the tip of the little finger, when the hand is stretched as far as possible
landmark of data a notable feature of a data set; landmarks include the median, mode, mean, maximum, minimum, and range
maximum the largest amount; the greatest number in a set of data
minimum the smallest amount; the smallest number in a set of data
median the middle value in a set of data when the data are listed in order from smallest to largest or vice versa. If there is an even number of data points, the median is the mean of the two middle values
mode the value or values that occur most often in a set of data
range the difference between the maximum and the minimum in a set of data
stem-and-leaf plot a display of data values in which digits with larger place values are "stems" and digits with smaller place values are "leaves"
normal span the distance from the end of the thumb to the end of the index finger of an outstretched hand
quick common denominator (QCD) the product of the denominators of two or more fractions
simplest form of a fraction a fraction that cannot be renamed in simpler form (reduced)
sample a part of a population intended to represent the whole population
survey a study that collects data
unlike denominators denominators that are different
