  1. Graphing Your Data Showing patterns & trends A picture is worth a thousand words!

  2. Types of data (information) • Variables • what you measure in an experiment • dependent variable • measured variable • unpredictable change: we don’t know how it will change until we do the experiment • Y-axis • independent variable • manipulated variable • predictable change: it only changes because we chose how it would change • X-axis The effect of _____________on _____________ INDEPENDENT DEPENDENT

  3. Examples of experiments 1 • How does fertilizer affect the growth rate of plants? • we set up an experiment testing different amounts of fertilizer on different plants & measuring the growth (height) of the plants: • dependent variable (Y-axis)? • height of plants • independent variable (X-axis)? • amount of fertilizer The effect of _____________on _____________ Amount of Fertilizer Height of Plants

  4. Examples of experiments 2 • How does exercise affect heart rate of 10th grade student? • we set up an experiment testing different lengths of time of exercise (minutes) on the heart rate of students: • dependent variable (Y-axis)? • heart rate • independent variable (X-axis)? • minutes of exercise The effect of _____________on _____________ Exercise Heart Rate

  5. Examples of experiments 3 • What’s the favorite drink of students? • we set up an experiment surveying students and asking which is their favorite drink : • dependent variable (Y-axis)? • number of students • independent variable (X-axis)? • type of drink The effect of _____________on _____________ Type of Drink How many students chose it

  6. Making pictures out of data How’s a critterto choose? • Graphs • line graphs • graphing data that shows continuous change • bar graphs (or histograms) • graphing data that is in disconnected groups
