Question

Listed below are the errors between the predicted temperatures and actual temperatures of a certain city. Find the mean and median for each of the two samples. Do the means and medians indicate that the temperatures predicted one day in advance are more accurate than those predicted 5 days in advance, as we might expect? (actual high)-(predicted high 1 day earlier) (actual high)-(predicted high 5 days earlier) 1 2 1 2 1 3 1 -5 1 -2 1 -1 0 2 1 2 0 -3 -3 2 The mean difference between actual high and the predicted high one day earlier is The median difference between actual high and the predicted high one day earlier is The mean difference between actual high and the predicted high five days earlier is the median difference between actual high and the predicted high five days earlier is

Explanation / Answer

The mean difference between actual high and predicted high one day earlier is 0.5 (Ans).

The median difference between actual high and predicted high one day earlier is 1. (Ans).

The mean difference between actual high and predicted high five days earlier is 0.1. (Ans).

The median difference between actual high and predicted high five days earlier is 0.5 . (Ans).

The means and medians indicate substantial difference in accuracy, mean and median is higher for

difference between actual high and predicted high one day earlier
