Statistically speaking; a sure thing.
Most people are not statistically trained so the probability of whether or not you are forecasting is so close to 0 that knowing its value is of little help.
No, it is not.
Data is statistically significant if the p (probability) value is below a certain level (ex: 5% or 1%). The p value describes how often one would receive the results they got if left to chance alone. The lower the p value, the less likely it is that your results were due to chance and is stronger evidence against the null hypothesis. Also important to keep in mind is that just because something is statistically significant does not mean it is practically significant.
