Column charts - ✔Use to compare data across categories( requires
categorical or ordinal data, displays variables vertically)
Line graphs - ✔Use to display continuous data over time
Histogram - ✔Use to visually display normality ( normal distribution of
continuous/quantitative /frequency of data around the mean) for a set of
data points
Pie charts - ✔Use when you have one row or column of data and you want to
know how much one data point is in relation to the whole. Especially useful
when displaying portions or percentages
bar chart - ✔Similar to column charts but better to use when your labels are
long ( categorical or ordinal data, there are spaces between bars and it is
displayed horizontally)
x-y scatter plot - ✔Shows the relationship among numeric values in several
data series, or plot two groups of numbers as one series of XY coordinates
( requires continuous data)
donut chart - ✔Show the relationship of parts to a whole like a pie chart but
can contain more than one data series( can be continuous or categorical
sections of a whole)
Bubble charts - ✔Are continuous data that are arranged in columns on a
worksheet so that the X values are listed in the first column and the
corresponding Y values and bubble size values s are listed in adjacent
columns.
Geospatial maps - ✔Visually depict the prevalence and occurrence of a
condition or disease geographically using polygons. The are 2 types of data
used in mapping- vector data and raster data
Raster Data - ✔A grid-based format for storing location-based data in a
geographic information system in which each equally-sized cell or pixel
contains a value that represents geographic data such as land.
Vector Data - ✔A format for storing location-based data in a geographic
information system that uses latitude and longitude coordinates to represent
geographic features with points, lines, and other complex shapes.
