CAUSATION: 1. Which relationship can best be described as causal? (1) The alarm goes off and the sun rises. (2) The car is moving slowly and the driver is singing. (3) The birds are chirping and the rain is coming down. (4) The snow is falling and the stores run out of snow shovels. CORRELATION COEFFICIENT: The value of is always in the range _____________________. r If is close to 1, the data shows a ________________________ correlation. r If is close to -1, the data shows a _______________________ correlation. r If = 0, the data does show a ______________________ correlation. r not If , the looks like: If , the graph looks like:
