Graphing In Science

Graphing In ScienceGraphingGraphs are a useful tool in science.The visual characteristics of a graph make trends in data easy to see. One of the most valuable uses for graphs is to show data collected during an experiment. The graph shows your results.

Why Do We Use Graphs?Graphs help us visualize numerical data.There are 3 different types of graphs:Bar graphsPie graphsLine graphs

The cafeteria wanted to collect data on how much milk was sold in 1 week. The table below shows the results. We are going to take this data and display it in 3 different types of graphs.Bar GraphA bar graph is used to show relationships between groups.The two items being compared do not need to affect each other.It's a fast way to show big differences. Notice how easy it is to read a bar graph.

Circle Graph or Pie GraphA circle graph is used to show how a part of something relates to the whole.This kind of graph is needed to show percentages effectively.

Line GraphA line graph is used to show change over time.It's clear to see how things are going by the rises and falls a line graph shows.

MondayGraphing StepsIdentify the VariablesNumber and label each axisPlot the pointsDraw the graphGive your graph a titleIdentify the VariablesIndependent Variable - (the thing you changed) Goes on the X axis (horizontal) Should be on the left side of a data table. Dependent Variable - (changes with the independent variable) Goes on the Y axis (vertical) Should be on the right side of a data table.

Label Axis'sYou need to tell everyone reading your graph what the graph means.Be sure to include units.Chart153721123376
