A researcher hypothesized that imagery instructions would improve the recall of words. In her

experiment,

she randomly assigned some participants to learn a list

of words with the instruction to

use imagery. Participan

ts in the second group

were instructed to learn the words with rote

memorization,

whereas the third group used a

combination of rote and imagery memorization

strategies. The following represent the number of words recalled by each of the groups.

Imagery:

34, 32, 11, 34, 32,

29, 29, 28, 25, 2

7, 28, 39, 35, 3

2, 22, 21, 22, 33, 29, 24, 32, 33, 33, 22, 29, 33, 21

Rote:

12, 12, 18, 19, 20, 20,19,18, 21

, 11, 13, 12, 10, 10, 11, 11, 12, 11, 12, 12, 11, 10, 12, 22, 14, 21, 11

Combination

32, 2

6, 17, 12, 13, 16,

12, 12, 11, 10, 12, 22, 14, 21, 11, 11, 10, 12, 13,

14, 23, 18, 12, 11, 9, 1

8, 19

Determine from the data whether imagery instructions were superior as

compared to the other

strategies.
