Predict the correlation for each example: I. How many days of school you miss V.S the mark you receive in your report card II. How long you study V.S the mark on exams III.The speed of a car V.S the stopping distance
I. The more days you miss school the mark decreases. II. The longer you study, your marks increases. III. The faster the car drives, the stopping distance increases (the more the car stops).
