Question 1 [Explained]
Analyze a dataset that records Earth's average yearly temperatures every fifty years. Tami is developing a trend analysis by calculating the formula for a line to illustrate the overall temperature trend. She uses the temperature records for the years 1708 (8.73 degrees) and 1958 (9.45 degrees) as reference points for her trend line.
The question involves using a dataset to track average yearly temperatures over a long period. Tami is calculating a trend line using two specific data points from the years 1708 and 1958 to show the overall temperature trend.
Year (x) | 1708 | 1758 | 1808 | 1858 | 1908 | 1958 | 2008 |
Temperature °C ( y) | 8.73 | 9.22 | 9.10 | 9.12 | 9.13 | 9.45 | 9.76 |
Question 1 [a] [Explanation]
