Question

Do you think predicting and inferring are just the same?(why?)​

Answer 1

I think they are the same! Predicting is what you think will happen or what the outcome will be, while inferring is pretty much the same thing!

Answer 2

Answer:

Inference:

 You want to find out what the effect of Age, Passenger Class and, Gender has on surviving the Titanic Disaster. You can put up a logistic regression and infer the effect each passenger characteristic has on survival rates.

Prediction: 

Given some information on a Titanic passenger, you want to choose from the set {lives,dies}{lives,dies} and be correct as often as possible. (See bias-variance tradeoff for prediction in case you wonder how to be correct as often as possible.)
