Lesson
Let's construct a model.
Exercise \(\PageIndex{1}\): California Rain
What do you notice? What do you wonder?
Exercise \(\PageIndex{2}\): Data Snooping
The table shows the average high temperature in September for cities with different latitudes. Examine the data in the table.
| city | latitude (degrees North) | temperature (degrees Fahrenheit) |
|---|---|---|
| Atlanta, GA | \(33.38\) | \(82\) |
| Portland, ME | \(43.38\) | \(69\) |
| Boston, MA | \(42.22\) | \(73\) |
| Dallas, TX | \(32.51\) | \(88\) |
| Denver, CO | \(39.46\) | \(77\) |
| Edmonton, AB | \(53.34\) | \(62\) |
| Fairbanks, AK | \(64.48\) | \(55\) |
| Juneau, AK | \(58.22\) | \(56\) |
| Kansas City, MO | \(39.16\) | \(78\) |
| Lincoln, NE | \(40.51\) | \(77\) |
| Miami, FL | \(25.45\) | \(88\) |
| Minneapolis, MN | \(44.53\) | \(71\) |
| New York City, NY | \(40.38\) | \(75\) |
| Orlando, FL | \(28.26\) | \(90\) |
| Philadelphia, PA | \(39.53\) | \(78\) |
| San Antonio, TX | \(29.32\) | \(89\) |
| San Francisco, CA | \(37.37\) | \(74\) |
| Seattle, WA | \(47.36\) | \(69\) |
| Tampa, FL | \(27.57\) | \(89\) |

| Yellowknife, NT | \(62.27\) | \(50\) |
- What information does each row contain?
- What is the range for each variable?
- Do you see an association between the two variables? If so, describe the association.
Exercise \(\PageIndex{3}\): Temperature vs. Latitude
1. Make a scatter plot of the data.
2. Describe any patterns of association that you notice.
3. Draw a line that fits the data. Write an equation for this line.
