I am creating a study and need to answer this question: Does the type of retrieval test given to children affect memory performance?In order to answer this question, I randomly assigned children to unequal-sized groups.Both groups were asked to memorize a list of eight words.In the Explicit testing condition, children were asked to recall the items in any order.In the Implicit testing condition, children were given a word-stem completion task for each list item, and they were then asked to fill in the first word that came to mind.The dependent variable was the number of items correctly recalled.The results were:

For the Explicit Group (E)

n₁=52=3.65=1.22

For the Implicit Group (I)

n₂=45=5.90 =2.50

a)State H₀

b)Compute

c)Compute t

d)What is the critical t-value if ₂ = .05?

e)Do you reject H₀ at ₂ = .05? Explain your decision.

f) What conclusion do you draw about the results of this experiment?

g)Express the mean difference as an effect size.
