The value of the mean absolute percent error (mape)
What is mean?
Mean is an average value calculated by adding a set of numbers and then dividing by the number of items in the set. It is a measure of central tendency in a set of data and is often used to describe the overall trend or pattern in the data. Mean can also be used to compare sets of data and is often used to compare the performance of different groups of people or businesses.
The mean absolute percent error (MAPE) is a measure of the accuracy of a forecast. It is calculated by taking the mean of the absolute percent errors (the difference between the forecast and the actual value), divided by the mean of the actual values.
For the given data, the MAPE is calculated as follows:
MAPE = (|18.00 - 17| + |20.00 - 25| + |15.00 - 14| + |14.00 - 23|)/(17 + 25 + 14 + 23) = 0.30
Therefore, the mean absolute percent error (MAPE) for the given data is 0.30.
