graphing in excel did someone say giraffing in excel? no, that would be graphing in excel!
TRANSCRIPT
Let’s begin.
First you need some data to graph.
Since this is your first time, we will supply you with some data.
This is real data from the giraffe population of Niger.
Now you’re talking!!
Giraffe Population in Niger over Time
Year 1996 2000 2006 2009 2010
Total number of giraffes
50 87 135 200 310
There used to be thousands of giraffes in Niger. In 1996, there were only 50 left . Many people have worked hard to help save these giraffes from extinction.
Since this data shows how the population changed over time, we are going to make a line graph.
Okay..
I’m cool with that.
Entering data into a spread sheet.
1. Data should be entered vertically. 2. The independent variable should go in the first column.3. The dependent variable should go in the second column.In this study, which is the independent variable?If you said the date, you are correct.The population of giraffe depends on what year it is because it changed over time.The number of giraffes was determined by measuring (counting them!)
3. Now enter each value for year and the corresponding number of giraffe.
Make sure they are lined up correctly.
1996 50 2000 87 2006 142 2009 200 2010 310
Fun, right?
Now we’re going to make the graph.Move your mouse over the columns of data starting at the upper left until you have highlighted all the data. (Don’t include the headings, just the numbers!)
Did someone say Mouse?!
They meant me, silly!
On the tabs on top, click on “Insert.”
After you click, you will see a colorful collection of charts.
It should have changed to look like this:You must always give your graph a title and label both axes.
This is the ‘’y” axis.
This is the ‘’x” axis.
Just click on them one by one and type in this title and these labels:
And click on this and delete it.
Do you think the giraffe conservation efforts in Niger are succeeding?
We have a way to go, but things are looking up!
I always look up to
you!
