ACTUAL Questions and CORRECT
Answers
frequency distribution - CORRECT ANSWER - presents the frequency of every value in a
dataset
frequency tables - CORRECT 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? - CORRECT ANSWER - one
column represents the category, the other column represents the frequency
absolute frequency - CORRECT 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?"? - CORRECT ANSWER - relative frequency
relative frequency - CORRECT ANSWER - the ratio between the absolute frequency of a
category and the total frequency
formula for relative frequency - CORRECT 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?"? - CORRECT ANSWER - cumulative frequency
cumulative frequency - CORRECT ANSWER - the sum of frequencies of all preceding
categories
, Frequency tables can be used for what type of variables? - CORRECT ANSWER -
qualitative or quantitative variables
When using frequency tables for quantitative variables, group the quantitative scores into groups
called what? - CORRECT ANSWER - bins
frequency graphs - CORRECT ANSWER - pie charts, bar charts, histograms, frequency
polygons, stem and leaf plots
What type of frequency graphs are used for qualitative variables? - CORRECT
ANSWER - pie charts and bar charts
What type of frequency graphs are used for quantitative variables? - CORRECT
ANSWER - histograms, frequency polygons and stem and leaf plots
pie charts - CORRECT ANSWER - displays relative frequencies (and not necessarily
absolute frequencies) of each category for qualitative variables in a pie
Each portion of a pie represents... - CORRECT ANSWER - a different category
The size of each portion is proportional to... - CORRECT ANSWER - the relative
frequency of that category
The entire pie represents... - CORRECT ANSWER - 100% of the scores
Pie charts are good to visualize... - CORRECT ANSWER - frequencies
Pie charts are only useful for... - CORRECT ANSWER - small number of categories
