Skill 4: Know which type of graph to use for each type of data...discrete, continuous, or parts of a whole.
Skill 4: Know which type of graph to use for each type of data...discrete, continuous, or parts of a whole.
Discrete data - data which falls clearly into one category or another. Bar graphs are good for discrete data.
Discrete data - data which falls clearly into one category or another. Bar graphs are good for discrete data.
Example: In the bar graph, a pet is either a rabbit, dog, cat, goldfish, or hamster. There is no "in between" category such as a "catdog!"
Continuous data - data in which you can find a point between two other data points.
Continuous data - data in which you can find a point between two other data points.
Example: If you have one data point at 3 and another at 5, you can find the point 4 in between them. You should draw a line from 3 to 5, which passes through 4.
Pie graphs show parts of a whole. The sum of all parts must add up to 100%.
Pie graphs show parts of a whole. The sum of all parts must add up to 100%.
Example: What percent of Mrs. Baker's classes like oranges the best?

Skill 5: Draw an appropriate conclusion from a graph.
Once the data is analyzed, a conclusion is drawn which is justified by the data. It's like the missing piece of the puzzle which ties everything together, once set into place.

Theory
Theory
A theory is an idea to explain a law, or observed natural phenomenon. A hypothesis which is very well supported from a variety of sources will eventually become a theory. One scientist cannot create a theory; he can only create a hypothesis.
