1 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

2 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

3 Water Released and Absorbed by Tree Time Absorbed by Roots (g/h) Released by Leaves (g/h) 8 AM 10 AM 12 PM 2 PM 4 PM 6 PM 8 PM 5 2 10 14 9 6 4 1 1 12 17 16 10 3 Water released by leaves Water absorbed by roots Relative Rates (g/h) 20 Time 0 15 10 5 8 AM10 AM12 PM2 PM4 PM6 PM8 PM Making a Graph From A Data Table

4 All Graphs Should Have! Title Label of the axis’ A consistent scale Units Key (if needed) *It should take up as Much space as possible

5 Line Graphs Line Graphs- compares sets of data, show change and patterns over time.

6 Number of plant sprouts per day for plants A and B DaySprouts Plant A 110 215 322 435 541 650 Sprouts Plant B 2 13 15 20 21 -Get a piece of graph paper

7 Homework: Graphing Practice Worksheet Front side only!! (Name side) 1 graph per graph paper side Answer questions on handout!! Be sure to determine the independent and dependent variable…Cause/Effect

How To Make a Graph (The Right Way)

How To Make a Graph (The Right Way)
Graphing Guidelines  Often the goal of an experiment is to find the relationship between two variables.  As one variable changes, so does the other.

Organizing Data A graph is a pictorial representation of information recorded in a data table. It is used to show a relationship between two or more factors.
