Biology: Please get out a sheet of GRAPHING paper for graphing notes!!! HOMEWORK Graph practice Today: 9/15/2014 Graphing Practice!! Learning Objectives: Analyze Data by making a graph
Graphs Give a visual representation of data Summarizes data. Two types of variables –Independent variable the thing you have control over { x-axis } –Dependent variable the thing that you don’t have control over (What you measure). { y-axis } D R Y M I X D-Dependent variable R- Responding variable Y- (goes on) Y-axis M-Manipulated variable I-Independent variable X-(goes on) X-axis
