Do I Have to Write This Down?
• Up to you• How do you learn?– Writing? Reading? Listening?
![Page 3: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/3.jpg)
Um, what type of graph should I do?
• First Things first: When appropriate…• DRY MIX– Manipulated (independent) variable is plotted on
the x-axis (MIX)
– Responding (dependent) variable is plotted on the y-axis (DRY)

Line Graph
• Used to track changes over time– If time is not one of your variables, then it can’t be
a line graph• Also used to compare changes over the same
period of time for more than one groups
• We use line graphs often in this class
![Page 5: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/5.jpg)
Line Graphs: Changes over time
• “Over time” indicates that time is on the x-axis
![Page 6: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/6.jpg)
Pie Charts
• Pie charts are best to use when you are trying to compare parts of a whole – No change over time– Not used often in this class
– The ONLY thing you need to know about pie charts is that we don’t use them in this class…

Pie Charts: parts of a whole

Bar Graphs
• For changes for a group or category of things – Not usually for numbers; mostly for things– Very rarely used for this class
– The ONLY thing you need to know about bar graphs is that we don’t use them in this class…
![Page 9: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/9.jpg)
Bar Graph - categorical data
Always a key
![Page 10: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/10.jpg)
Choosing Appropriate Graphs…
• Bar Graph - categorical data – graphing things or “categories” on the x-axis
![Page 11: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/11.jpg)
X-Y Plots (Scatter Plots)
• X-Y plots (scatter plots) are used to determine relationships between the two different things – We use this a lot in this class
![Page 12: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/12.jpg)
Trend Line
![Page 13: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/13.jpg)
X-Y Plots (Scatter Plots)
• Often they need a trend (best fit) line – A line on a graph showing the general direction
that a group of points seem to be heading – NOT “Connect the dots” – Although it might seem like it if your data is linear – The idea is to try to get a line that has virtually
equal numbers of points on either side
![Page 14: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/14.jpg)
Best Fit Line or Trend Line
Not “connect the dots”
![Page 15: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/15.jpg)
Choosing the Correct Graph Type
• In science class, you will use line graphs and scatter plots– It is very rare that you will use anything else
![Page 16: Graphing Info Pay Attention. Getcho lab. Do I Have to Write This Down? Up to you How do you learn? Writing? Reading? Listening?](https://reader036.vdocuments.net/reader036/viewer/2022062401/5a4d1b767f8b9ab0599b73db/html5/thumbnails/16.jpg)
ISD MS Physical Science Graphing Rubric
• Chose the wrong graph type? – No points for you!
• Got your axis mixed up? – No points for you!
• No units or variables on your axis? – No points for you!
• Connected the dots on a scatter plot? – No points for you!
