frequency distribution - answer--presents the frequency of every value in a
dataset
frequency tables - answer--displays the number of times (ex: frequency) a certain
value appears within the dataset in a table format
What does each column represent in frequency tables? - answer--one column
represents the category, the other column represents the frequency
absolute frequency - answer--raw count
What type of frequency do you use when answering " how many student out of
the total number of students scored a letter grade?"? - answer--relative frequency
relative frequency - answer--the ratio between the absolute frequency of a
category and the total frequency
formula for relative frequency - answer--frequency in category/total frequency
What type of frequency do you use when answering the question "how many
students scored a B or better?"? - answer--cumulative frequency
, cumulative frequency - answer--the sum of frequencies of all preceding categories
Frequency tables can be used for what type of variables? - answer--qualitative or
quantitative variables
When using frequency tables for quantitative variables, group the quantitative
scores into groups called what? - answer--bins
frequency graphs - answer--pie charts, bar charts, histograms, frequency
polygons, stem and leaf plots
What type of frequency graphs are used for qualitative variables? - answer--pie
charts and bar charts
What type of frequency graphs are used for quantitative variables? - answer--
histograms, frequency polygons and stem and leaf plots
pie charts - answer--displays relative frequencies (and not necessarily absolute
frequencies) of each category for qualitative variables in a pie
Each portion of a pie represents... - answer--a different category
The size of each portion is proportional to... - answer--the relative frequency of
that category
