AKA the most fun you’ve ever had  Graphing AKA the most fun you’ve ever had 

5 steps to making a complete graph.. 1. Title your graph (title tells the independent variable and dependent variable) 2. Determine your I.V. and D.V. Independent variable (I.V.)- what the experiementer changes (maniplates) Dependent variable (D.V.)-what’s being measured 3. Draw axis Scale the graph and label X and Y axis 4. Plot data 5. Make a conclusion statement

Scaling.. Scales are number patters that you will use when labeling your graph Examples: 2, 4, 6, 8, 10.. 5, 10, 15, 20.. 10, 20, 30, 40.. See the scale?

Labeling.. You must label your graph in order for it to be properly read or understood. Without proper labeling, it would just be bars or lines on a page. The I.V. is always labeled on the X axis The D.V. is always located on the Y axis!

Labeling.. Where do they go? I.V. Always on x-axis D.V. y-axis

3 types of graphs.. 1. bar graph Used for categories Example: Months Animals Cars Etc..

3 types of graphs continued.. 2. line graph Used to show trends or things that happen over time Notice that both sides are scaled!

Trends Upward trend The data amounts plotted increases over time

Trends continued.. Downward Trend The data amounts plotted decrease over time

3 types of graphs continued.. 3. circle graph AKA pie chart Used for percentages

What kind of graph would you use here? A researcher is trying to show the percentage of pine trees in a forest compared to 3 other species. A census worker is trying to explain growth trends in the human population over the next 50 years. A game warden is explaining deer population numbers to hunters from Mississippi, Alabama, Louisiana, and Arkansas.
