Front 1

frequency distribution

Back 1

display table dividing certain values into a set f classes and showing the number of observations falling into each class

Front 2

mutually exclusive

Back 2

the classes in a frequency distribution are mutually exclusive when each data value can fall into only one category

Front 3

exhaustive

Back 3

the condition in which the set of classes includes all possible data values

Front 4

relative frequency distribution

Back 4

the display table showing the proportion of times an event occurs over a large number of trials

Front 5

cumulative frequency distribution

Back 5

showing the number of observations within or below each class, or above or within each class

Front 6

histogram

Back 6

for quantative variables, a graphical method that describes a frequency distribution by expressing either the frequency or relative frequency within each class as the length of a rectangle... in a histogram, adjacent rectangles share a common side

Front 7

ogive

Back 7

a graphical display providing cumulative values for frequencies, relative frequencies, or percentages. may be either less than or greater than

Front 8

bar chart

Back 8

for qualitive variables, a graphical method in which the number of values in a category is proportional to the length of a rectangle. unlike the histogram, there is a gap between adjacent rectangles
