• y-axis
• plot points

You want to have your data be clustered into common characteristics. What would you use

• unsupervised

The Nieve Bayesian Algorthm assumes all the predictors are __

• dependent on each other
• independent of each other

You have five predictors, but one of the predictors is the most important in determining the result. What should you use?

• Weighted Multiplier
• Trend LIne
• Plot Points

Why is K-nearest neighbor also called lazy learning

• it uses a lot of computation for every instance
• It accumulates knowledge very slowly
• It borrows ideas from several other models
• It is very computationally efficient

What should you do if your decision tree has too much entropy?

• Add or substitute predictors
• add more outcomes
• choose a different root
• Delete the leaves

Which do you use when looking for trends instead of classifying data into different groups

• regression problems
• binary classification
• multiclass classification
• unsupervised learning
