Does Elevation Affect Temperature Mid-June?
Suppose that you wanted to determine the effect, if any, thatelevation has on temperature. The table below lists the elevations(in feet above sea level) of 24 randomly selected cities in theUnited States and the low temperatures (in degrees Fahrenheit) ofthese cities on June 15, 2020.
Elevation | 1365 | −282 | 5280 | 4551 | 6910 | 6063 | 3875 | 2730 | 7 | 1201 | 2001 | 1843 |
Low Temp. | 56 | 79 | 56 | 56 | 39 | 55 | 42 | 51 | 74 | 63 | 73 | 48 |
| | | | | | | | | | | | |
Elevation | 3202 | 2389 | 4226 | 1550 | 2134 | 2080 | −7 | 141 | 909 | 50 | 338 | 1086 |
Low Temp. | 64 | 73 | 56 | 53 | 58 | 57 | 80 | 55 | 74 | 56 | 69 | 78 |
- If Westerville is 875 feet above sea level, what isWesterville’s estimated low temperature for June 15, 2020?
- Before performing any regression analyses, what is the benefitof noting that the lowest and highest values amongst the elevationdata are −282 feet and 6910 feet, respectively?
- What proportion of the variation in low temperatures can beexplained by the linear relationship with elevation?
