AKA the most fun you’ve ever had
Graphing AKA the most fun you’ve ever had
2
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
3
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?
4
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!
5
Labeling.. Where do they go?
I.V. Always on x-axis D.V. y-axis
6
3 types of graphs.. 1. bar graph Used for categories Example: Months
Animals Cars Etc..
7
3 types of graphs continued..
2. line graph Used to show trends or things that happen over time Notice that both sides are scaled!
8
Trends Upward trend The data amounts plotted increases over time
9
Trends continued.. Downward Trend
The data amounts plotted decrease over time
10
3 types of graphs continued..
3. circle graph AKA pie chart Used for percentages
11
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.
