Making Graphs from Data. Bar, Line, or Pie? / One of the first things one needs to do when graphing is decide whether to make a bar graph or a line graph.

Graphs Graphs are used to display data. They visually represent relationships between data. All graphs should have a title that identifies the variables.

GRAPHS Bar, Line, Circle. Bar Graph A bar graph uses vertical or horizontal bars to display numerical information. Bar graphs can be used to compare amounts.

A graphical display should: Show the data Induce the viewer to think about the substance of the graphic Avoid distorting the message.

Bar Graphs Used for comparing separate groups. Axes X- axis: independent variable (what the scientist controls) Horizontal D – dependent R – responding.

A histogram is a special type of bar graph used to display numerical data that has been organized into intervals. The heights of the bars show the number.

Amount of energy drink (ml) Step 5: Analyze the Results How To Do A Graph Draw an x-axis (horizontal) and a y-axis (vertical). The axes represent different variables: The x-axis represents the independent variable. The y-axis represents the dependent variable. Choose the scale for each of the axes (evenly spaced intervals that include all of your data) Plot your data on the graph. Label the axes with the appropriate units. Give your graph a title. A good title should explain the relationship between the variables. Organize data (tables and graphs) and analyze results. Explains the effect of the variable. Amount of energy drink (ml) 10 20 40 80 100 Time awake (h) 6.0 8.2 12.5 20.2 26.6 4/27

TYPES OF GRAPHS Line: show relationships; for continuous data Bar: compare data; for discrete data. Combination: two data set with the same independent variable Histogram: frequency of occurrence of a data set Scatterplot: show positive, negative or no correlation (dependence) between the variables Circle: parts of a whole (percentages).

Amount of energy drink (ml) Practice! A student wanted to test how the consumption of energy drink affect the time a subject can be awake. Amount of energy drink (ml) 10 20 40 80 100 Time awake (h) 6.0 8.2 12.5 20.2 26.6 1. Is there any control group in this data? 2. What should it be? 3. Why would it be important to have?

Step 5: Analyze the Results Real Case: The Deformed frogs in Minnesota Group UV light exposure (days) Deformed frogs 1 2 5 3 10 8 4 20 22 Organize data (tables and graphs) and analyze results. Explains the effect of the variable. Conclusions 20 15 10 5 30 25 Effect of UV light exposure have over the frogs deformities Is the hypothesis supported? What are the implications of the result? What things should be tested to improve the results? Data shows that the length of the UV exposure has an effect on the development of frog deformities Deformed frogs UV light exposure (days) 4/27

TYPES OF GRAPHS Line: show relationships; for continuous data Bar: compare data; for discrete data. Combination: two data set with the same independent variable Histogram: frequency of occurrence of a data set Scatterplot: show positive, negative or no correlation (dependence) between the variables Circle: parts of a whole (percentages).
