1. Graphs How to set up successful graphs in Mrs. Mulcrone’s class!

2. How to set up your graph!

3. Y Axis (This is for your dependent variable)

4. How to set up your graph! X Axis (This is for your independent variable)

5. TAILS T T - Title Teachers’s Favorite Singer

6. TAILS T - T - Title A - Axis Teachers’s Favorite Singer Y Axis = Dependent Variable X Axis = Independent Variable

7. TAILS T - T - Title A – Axis S – Scale Teachers’s Favorite Singer Decide on an appropriate scale for each axis. Choose a scale that lets you make the graph as large as possible for your paper and data

8. How to determine scale Scale is determined by your highest & lowest number. In this case your scale would be from 2 – 22. Favorite Singer Number of Teachers Toby Keith22 Madonna15 Elvis11 Sting5 Sinatra2

9. How to determine Intervals The interval is decided by your scale. In this case your scale would be from 2 – 22 and you want the scale to fit the graph. The best interval would be to go by 5’s. Favorite Singer Number of Teachers Toby Keith22 Madonna15 Elvis11 Sting5 Sinatra2

10. TAILS T – Title A – Axis I – Interval S – Scale Teachers’s Favorite Singer The amount of space between one number and the next or one type of data and the next on the graph. The interval is just as important as the scale Choose an interval that lets you make the graph as large as possible for your paper and data

11. TAILS T – Title A – Axis I – Interval S – Scale Teachers’s Favorite Singer 0 5 10 15 20 25

12. TAILS T – Title A – Axis I – Interval L – Labels S – Scale Teachers’s Favorite Singer 0 5 10 15 20 25 Toby Keith Madonna Elvis Sting Sinatra LABEL your bars or data points Singers Give the bars a general label. What do those words mean? Number of Teachers Label your Y Axis. What do those numbers mean?

13. When to use… Bar graphsBar graphs –Used to show data that are not continuous. –Allows us to compare data like amounts or frequency or categories –Allow us to make generalizations about the data –Help us see differences in data Line GraphsLine Graphs –For continuous data –useful for showing trends over time

14. Quantitative vs. Qualitative There are two basic types of observations: Quantitative and Qualitative Quantitative observations are observations that involve a number in the form of an amount or measurement. Noticing that there are 12 students working in the library is a quantitative observation. Scientists try to use quantitative observations as much as possible because they are more accurate and precise.
