Graphs tell a story what story does this graph tell

Graphs Tell a StoryWhat story does this graph tell?


W hat story does this graph tell without labels and units it is difficult to know the story

What story does this graph tell? – Without Labels and units, it is difficult to know the story….

Water Depth

inches

Time minutes


It is also important to include a title to specifically describe what the data pertains to

Water level in a bathtub

It is also important to include a title to specifically describe what the data pertains to.

Water Depth

Your turn

Your turn…..

  • Draw a graph of an event, and describe the event with words (write a story).

  • Include labels, units, and a title with your graph.


Shapes of graphs

Shapes of graphs.

  • In nature, there are only a few basic graph shapes that describe many phenomenon such as gravity, light intensities, growth and decay rates, etc.

  • In this class, we will focus on four of these shapes of graphs.

  • In science, the objective of a graph is often to describe the relationship between the independent and dependent variables.

  • The relation between variables can be stated as an equation… The equation of the graphed line.


Graphs tell a story what story does this graph tell

  • If the graph is not yet a line (linear), but is one of the simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.


The linear graph

The Linear Graph


The graph of a square or graph of the independent variable raised to a power

The Graph of a SquareOr graph of the independent variable raised to a power.


The graph of a square root

The Graph of a Square Root


The graph of an inverse relation or graph of the independent x axis raised to the 1 power

The Graph of an Inverse relationOr graph of the independent x-axis raised to the -1 power.


Determine the relation which the given data describes
