data visualization Flashcards
graphical representation of data
data visualization
techniques used to communicate
insights from data through visual
representation.
data visualization
to distill large datasets into visual
graphics to allow for easy understanding
of complex relationships within the data
data visualization
to analyze massive amounts of informationand make data-driven decisions
data visualization
common visualization techniques
Bar Graph
Line Graph
Pie Graph
Histogram
Scatterplot
Boxplot
Heatmap
common visualization technique: used to compare counts, percentage, or other
measures (average) for different discrete
categories of data
bar graph
common visualization technique: used to observe trend
line graph
common visualization technique: shows the relative contribution that different categories contribute to an overall total
pie graph
common visualization techniques: shows the frequency distribution of continuous attribute
histogram
__ presents __ attribute while __ represents __ attribute
bar, categorical
histogram, numerical
t/f: bar graphs have spaces between bars, histograms do not
t
common visualization techniques: plots two numerical attributes
scatterplot
common visualization techniques: graphical representation of the quartiles
boxplots
common visualization techniques: graphical representation of data where the individual values contained in a matrix (map) are represented as colors
heat maps
t/f: bar graphs may be converted into radar charts
