Graphs- explained simply. What are graphs and examples.

 Graphs are sources of visual representation to display quantities of numerical data.

For example:

John surveyed the class to discover the most popular type of pet. His results were as follows.

Cat- 4

Dog- 12

Bird- 2

Hamster- 6

A. what is the most popular type of pet in John's class?.

B. How many students are in this class?.

C. Display this data.

 Zoning in on query 'C' of this question we are asked to display the data.

To display numerical data we can adjust a graph into the solution/final submission of this question/query. 

However, there is a large quantity of graphs to choose from. Ranging from bar charts to line plots it can be rather complex.

Bar charts

( Bar charts )

Bar charts are a graph consisting of vertical bars and the horizontal and vertical axis. The numerical source of the data ( in this case the quantities of students ) are situated precisely/accurately on the vertical axis, whilst the bars are specifically situated on the horizontal axis.

Please feel free to watch this YouTube video corresponding to the concept of bar charts:

The width of the bars must all be the same. And the space between the bars must be of the same length.

Line plots

Line plots are basically a line with accurate placements of bullet points. There are small 'x's above the bullet points to represent the data. The important thing with line plots is to be accurate and precise. Place the bullet points the same length away from each other and make sure your 'x's aren't too far away from each other. 

 Take a lot at some of those videos to get a better idea of the concept of line plots.
