scatter plot
A graph with points plotted to show a possible relationship between two sets of

A graph that displays changes in a variable at different points in time.
measure of central tendency
any value that represents a typical, or central, entry of a data set.
mean
an average of n numbers computed by adding some function of the numbers and
dividing by some function of n
midpoint
the sum of the upper and lower limits of a class divided by two
relative frequency
the portion or percentage of data that falls into a particular class (class
frequency/sample size)
cumulative frequency
the sum of the relative frequencies of a particular class and all previous classes
class boundaries
the numbers that separate classes without forming gaps between them
, 2
stem-and-leaf plot
a graph in which each number is separated into a stem and a leaf
dot plot
a graphical device that summarizes data by the number of dots above each data
value on the horizontal axis
histogram
a bar chart representing a frequency distribution
polygon graph
graph formed by joining the midpoints of the tops of successive bars in a
histogram with straight lines
ogive graph

boundary
pie chart
a circular chart divided into triangular areas proportional to the percentages of
the whole
pareto chart
a graph that shows the number of times something occurs, with categories
ordered from most frequent to least frequent
