Better data lead to better forecasts
Scientists turn to mathematical models to make good predictions. But if they don’t put good data into those models, they won’t get reliable forecasts. So good data are key.

Scientists Say: Outlier
Data points often fall within a normal range. When one data point sticks out a lot, it might be an outlier.
