data varies

Question 2

cause an effect

Answer 2

related to whether we say one variable is caused changes in the other variable versus other variables that maybe be related to these two variables

Answer 4

confidence interval

Question 5

the pattern of variation in data

Answer 5

distribution

margin of error

Answer 6

the expected amount of random variation in a statistic, often defined for the 95% confidence interval
