Question

a researcher measured the shoe size and reading ability of a large group of children. he found that, as shoe size increases, so does reading ability. what does his analysis show? (a) there is no correlation between shoe size and reading ability. there may or may not be causation. further studies would have to be done to determine this. there is a correlation between shoe size and reading ability. there is probably also causation. this is because there is an increase in reading ability with an increase in shoe size. a grocery store conducted a survey. it showed that when customers buy less oatmeal, it does not indicate a change in the amount of milk they purchase. what can we conclude? (b) there is no correlation between amount of oatmeal bought and amount of milk purchased. there is a correlation between amount of oatmeal bought and amount of milk purchased. however, there is no causation. this is because there is likely a decrease in the amount of milk purchased with a decrease in the amount of oatmeal bought. there is a correlation between amount of oatmeal bought and amount of milk purchased. there may or may not be causation. further studies would have to be done to determine this. all compared the player statistics from teams basketball season. he determined that being taller does not imply that a player scores more or fewer points. what is likely true? (c) there is no correlation between height and number of points scored. there is a correlation between height and number of points scored. there may or may not be causation. further studies would have to be done to determine this. there is a correlation between height and number of points scored. however, there is no causation. this is because there is probably an increase in the number of points scored with an increase in height.

Explanation:

(a) A positive correlation is found as shoe - size increases with reading ability, but correlation does not imply causation.
(b) There is a negative correlation between amount of milk and oatmeal purchased, but no causation is indicated.
(c) There is a positive correlation between height and points scored, but no causation is clear.

Answer:

(a) There is a correlation between shoe size and reading ability. There may or may not be causation. Further studies would have to be done.
(b) There is a correlation between amount of oatmeal bought and amount of milk purchased. There may or may not be causation. Further studies would have to be done.
(c) There is a correlation between height and number of points scored. There may or may not be causation. Further studies would have to be done.
