Is it normal to have your MAPE(Mean absolute percentage error) and MAE(Mean Absolute Error) be lesser for one month. I took a data set where my one day prediction was accurate. In another set, my one month was more accurate. What is a conclusion I can make. This is from Predict Water Quality with Random Forests

Re: Water Quality/
Hi there!
It is totally normal for your data to be more accurate over the course of a month compared to just a day, in fact, this a sign of validity. As you compile more data, the less impacts outliers will have on overall means and the more accurate your measures of central tendency are. So, your results are actually signs of a strong experiment.
