Data coping refers back to the technique of gathering, recording, and offering data in a way this is helpful to others. Data is commonly represented in the shape of pictographs, bar graphs, pie charts, histograms, line graphs, etc. The distinct ways of representing the facts are given below:
- pictograph
- pie chart
- bar graph
- line graph
- histogram
Pictograph
A pictogram is an illustration of information through the use of multiple photos or symbols. “In arithmetic, pictograms generally discover utility in standards that consist of document coping with. They assist to provide thought for the interpretation of data based totally on pictographic records.
For example, the pictogram underneath suggests information for distinctive sorts of pizza that have been ordered on a random day.

They are useful in displaying statistical elements and styles. Line diagrams can create future expectancies about the results of records that might be now not recorded.
For example, the road graph beneath shows the biometrics of grade 7 college students inside the scholarship examination for 12 months from 2010-2016. Suggests percentage figures.

For example, the bar graph shows the information on the alternatives of a selected enjoyment among human beings.
