A statistical representation of data is a way to display numerical data in a graph. Graphs are useful for displaying data, but they can be difficult to read if the graph is too large or contains too many points. In statistics, it is important to use both tables and graphs to help analyze data.
Representation of data in statistics is the process of organizing information about a group or sample. This helps researchers better understand their data and find patterns within it that would not be apparent without visualizing them firsthand!
What skills are tested?
•Matching a data set to its graphical representation
•Matching a graphical representation to a How are qualitative data displayed?
Data displays can relate a qualitative variable and a quantitative measure such as a count or percent How are quantitative data displayed?
Data displays for quantitative data are typically oriented along two numerical axes and relate two quantitative variables How are trends over time displayed?
are data displays that show trends over time. These graphs typically present time (e.g., day, month How are relationships between variables displayed?
display data about two quantitative variables as a set of points in the xy -plane Your turn!

Log Representation of data in statistics is the process of organizing information about a group or sample. This helps researchers better understand their data and find patterns within it that would not be apparent without visualizing them firsthand! The most common types are
line graphs, bar charts, pie charts, histograms, and scatter plots.
The most common forms of representation for categorical (or categorised) data are the bar chart or pie graph. For numerical data, the number of data values will affect the selection. The most appropriate form of representation for smaller numerical data sets is likely to be the stacked dot plot or the stem-and-leaf plot.
The transformation of data through visual methods like
graphs, diagrams,maps and charts is called representation of data. Such a form of the presentationof data makes it easy to understand the patterns of population growth,distribution and the density, sex ratio, age–sex composition, occupationalstructure, etc. within a geographical territory.
