Example 3: Use Excel to create a plot of Toad Growth The following table

shows the land area in Australia colonized by the American marine toad (Bufo marinis).

Let’s make a plot of Year vs. Area on a Cartesian coordinate system (Year is on the x – axis …)

Year Area(km^2)

1939 32800

1944 55800

1949 73600

1954 138000

1959 202000

1964 257000

1969 301000

1974 584000

Making a Chart Open up a blank Excel

worksheet and enter the data for the toad population of Australia over time in the first two columns.

Highlight the cells with data including headings.

On the Insert tab, look in the Charts group for the different types of charts that can be chosen.

11

Step 1 – Chart Type The first thing we need to do is

to choose an appropriate chart to display the data – in this case we want to show the relationship between the toad population and a given year.

By moving the cursor over a type of chart, you will get a description of how the chart can be used.

A scatter plot compares pairs of values.

Click on the Scatter chart type and choose Scatter with only Markers (the top-left-most chart).

12

Step 2 – Chart Design and Location A chart will appear in the

sheet. In the Design tab (under

Chart Tools), use the Chart Layout and Chart Styles menus to adjust your chart if needed.

Choose a chart layout without any horizontal lines.

Also note that the chart can be moved to its own sheet via the Move Chart Location menu.

13

Step 3 – Chart Options In the Layout tab,

under the Design Tools, use the appropriate menus to remove the legend, add a Chart Title, and add axis labels (Axis Titles).

Other chart features can be adjusted from these menus.

For example, we can add a trendline.

14

Adding a Trendline Once we have a scatter plot, we

can try to find a curve that fits the data.

The simplest type of curve is a straight line or “best fit line”.

Right click on any data point in the chart and choose Add Trendline.

In the new window, choose Linear for the Trend/Regression Type and check the Display Equation on Chart box.

Here is the resulting chart with trendline included!

In this case, the best fit line is y = 13568 x – 3*10^7.

Making a Chart “Automatically” A chart can also be

made by highlighting the data to be put in the chart and pressing the F11 key.

The default chart is a bar chart.

From the Change Chart Type menu you can choose a new chart type and perform the same steps as above!

16

17

Importing data from a text file Often the data we

need is given as ASCII characters in a text file.

We can use Excel to open the file and help put the data into into “more usable” form.

18

Importing data from a text file (cont.) From Excel, open

up the text file that contains the data, with commas or spaces between each piece of data.

The Text Import Wizard will appear!

19

The Text Wizard Choose “Delimited”

and click Next. Choose Comma in

the Check-box and click Next.

Set the column formats and choose Finish.

The data should be in Excel!

Example 4: Create the following Function Table!

n n^2 n^3 4n^3+n^2-1 1+2+ … + n

1 1 1 4 1

2 4 8 35 3

3 9 27 116 6

4 16 64 271 10

5 25 125 524 15

6 36 216 899 21

22

Example 4 (cont.) Creating the first three columns in the table for

Example 4 with user-defined functions is straightforward.

For the last column, notice that if we let x(n) = 1+2+ … + n, then we have

x(1) = 1 x(2) = 3 = 1 + 2 = x(1) + 2 x(3) = 6 = 1 + 2 + 3 = x(2) + 3 … In general, x(n) = x(n-1) + n for n ≥ 2. Functions like this are called recurrence relations and

can be implemented with Excel!

23

Example 4 (cont.)

24

Example 4 (cont.) To print out a table that

appears on more than one page, choose the Page Layout tab.

Then choose either Print Titles or the dropdown menu from the Page Setup group.

Click on the Sheet tab and choose the rows to repeat at the top of each page!

Example 5: Sorting Data Excel is excellent for

sorting data in lists or tables!

For example, suppose we wish to sort a list of famous mathematicians by given Birth Year, Name, and Birth Year followed by Name!

First put the data into an Excel worksheet with Birth Year in column A and Name in column B.

Birth Year Name Birth Year Name

1584 Vernier 1840 Henrici

1646 Flamsteed 1852 Le, P.

1736 Bring 1900 Aiken

1739 Klügel 1878 Bernstein, F.

1939 Baker 1909 Black

1852 Frattini 1920 Pillai

1888 Courant 1946 Margulis

1924 Cohn 1880 Bernstein, S.

1942 Hawking 1796 Bienaymé

1814 Wantzel 1801 Cournot

1819 Adams 1867 Bôcher

1883 Keynes 1883 Schouten

1816 Wolf 1910 Turán

1905 Dubreil-Jacotin 1910 Koopmans

1906 Feller 1911 Kakutani

1922 Marchenko 1939 Kingman

1818 Joachimsthal    

27

Example 5 (cont.) To sort by Birth

Year, click on any cell in the Birth Year column (column A).

Then click on the Sort Smallest to Largest button.

Repeat with column B to sort by Name!

28

Example 5 (cont.) Another option is to

choose a cell within the data you wish to sort.

Then click on the Data tab and choose Sort.

The Sort menu allows recursive sorting in either ascending or descending order!

29

Example 5 (cont.) When working with

data, a useful tool for choosing portions of the data is the AutoFilter.

Select a cell in the data you wish to study, click on the Data tab, and choose the Filter button.

30

Example 5 (cont.) With the AutoFilter, you

can look at subsets of the data, for example the mathematicians born between 1600 and 1899.

To do so, choose the Number Filters menu in the first column and fill in the Custom AutoFilter accordingly.
