A meteorologist predicted that the downtown area would get 16 inches of snow in a snowstorm. The downtown area ended up getting 13 inches of snow. What was the percent error of the prediction?
3/16 = 0.1875 = 19% error
Thanks!
But how did you get 3/16?
16 - 13 = 3
There was a difference of three. I compared that with what was forecasted.
The correct answer is 23.1%
16-13=3
3/13=.230769...
So the answer is 23.1%
To calculate the percent error of the prediction, you need to find the difference between the predicted value and the actual value, and then express that difference as a percentage of the predicted value.
First, subtract the actual value (13 inches) from the predicted value (16 inches):
16 - 13 = 3
Next, calculate the absolute value of the difference:
|3| = 3
To find the percent error, divide the absolute difference by the predicted value and multiply by 100:
(3 / 16) x 100 = 18.75
Therefore, the percent error of the prediction is 18.75%.
