Can’t I just use a pie chart for everything?

2. Which graph fits your data?

3. Graphs A graph is a visual display of data or information.
In a graph the horizontal axis is called the x-axis.
In a graph the vertical axis is called the y-axis.
In a graph the independent variable is plotted on the x-axis and the dependent variable on the y-axis.
There are several types of graph that can be used to display data. Your data determines the kind of graph you need to use.

4. Scatter Plots - Find a Trend
A graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation/trend present.
Collection of points that have one value determining position on x-axis and a second value determining position on y-axis (plotting a point).

5. Plotted Points that show a relationship between variables.

6. Line Graph – What happens over time.
Uses points and line(s) to show how the data changes over a certain period of time, continuous change. Line graphs are useful for showing trends.
EXAMPLES
- Population changes in Fleming Island/Green Cove Springs over last few years
- Cost of smart phones since they came out
- Your height since you were a baby

7. Circle Graph
Compare parts of a whole. A circle graph is a circular chart divided into sections that each represent a percentage of the total.

8. Bar Graphs – Compare Categories
It is a graph where the IV is represented by categories and the DV is a number. Examples:
Amount of sugar in foods
Amount of students in clubs

9. Double Bar Graph Compare the size of two situations/variables.
You can compare and present more than one type of information using a double bar graph.
