What mistakes should MCA students avoid while learning predictive modelling?

Predictive modelling uses historical data to estimate likely future outcomes. Good practice includes choosing suitable features, avoiding data leakage and evaluating models on unseen data. If your target role involves predictive modelling, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the predictive modelling aspect of MCA study. For this specific question about predictive modelling, the practical takeaway is to relate the concept to your own MCA learning goal.
