Max Temperature
As we move towards equator, the hemisphere becomes significantly warmer. The regression analysis on both the hemispheres leads to better understanding!
-
The temperature depends on the distance from the equator.
- Observe the p-value of the linear regression estimator << 0. This means that the slope is NOT zero.
- In both hemispheres, a high correlation between latitude and temperature.
- We can observe a pattern in the scatter plot also.
- As we move towards equator, temperature increases on both sides of the hemisphere.
-
From the data, it looks like, temperatures at cities equidistant from the equator in both the sides might not be the same.
- For instance,
- At latitude +30, temperature is approximated as -0.45*30+89.53=76.03 F.
- At latitude -30, temperature is approximated as 0.75*(-30)+78.58 = 56.08F.
- This is because most of the northern hemisphere is land whereas most of the southern hemisphere is ocean and ocean is likely to be colder.
