Drawing conclusions 8. Predictions should include both an independent variable (the factor you change in an experiment) and a dependent variable (the factor you observe or measure in an experiment). Hypothesis will lead to explaining why something happened while prediction will lead to interpreting what might happen according to the present observations. So take a glance at the article presented below, which elaborates the difference between hypothesis and prediction. Prediction is the action of forecasting something which may o… If the individual gets eight hours of sleep, then the individual will be more productive.
