Graphing in Science

What are they? Graphs are pictures of your data and can reveal patterns and trends in data.

Types of Graphs Bar Graph Pie Graph Line Graph Scatter Plot Pictograph

The Uses of Graphs Pie graphs shows ratios of parts to a whole. Data is in percentages. Coconut

The Uses of Graphs Bar graphs show comparisons between collected data. The x and y data do not have to be numbers.

The Uses of Graphs Line graphs show how the dependent (y) variable changes in response to the independent(x) variable.

The Uses of Graphs Scatter Plots show a relationship between quantitative data collected in an experiment.

Plotting a Line Graph Draw axes Label axes Draw Scale Plot points Line of best fit Title

Relationship Between Data Positive Correlation Negative Correlation Line of best fit

Why Draw a Line of Best Fit? A line of best fit emphasizes the overall trend shown by all the data taken as a whole.

Slope (Rate of Change) The slope (rate of change) of a graph line tells you how much y changes for every change in x. Positive Correlation-shows that as one data set increases the other one also increases (up & up) Negative Correlation- shows that as one data set the other decreases.(up & down)

Car Travel The graph shows the distance a car travels in a one-hour period. Use the graph to answer the questions that follow.

Car Travel Reading Graphs: What variable is plotted on the horizontal axis? The vertical axis? Time (min), the independent variable, is plotted on the horizontal axis. Distance (km), the dependent variable, is plotted on the vertical axis.

Car Travel Interpreting Data: How far does the car travel in the first 10 minutes? In 40 minutes? The car travels 10 km in 10 minutes and 40 km in 40 minutes.

Car Travel Predicting: Use the graph to predict how far the car would travel in 120 minutes. Assume the car continues to travel at the same speed. The car is traveling 1 km per minute. It would travel 120 km in 120 minutes.

Car Travel Calculating: Calculate the slope (rate of change) of the graph. What information does the slope provide? The slope (rate of change) is 1 km/min. The slope (rate of change) provides information about the car’s average speed.
