Ethan carried out an experiment to investigate whether a new mnemonic technique improved word recall in children with mild learning difficulties. He compared a group of children who used the mnemonic technique (Condition X) with a group of children who used standard repetition (Condition Y).
Ethan collected the data from a spelling test administered to the children immediately after the learning session. The higher the score on the test, the better the child's word recall.
Ethan’s results are shown in Table 3.
Calculate the range of Condition Y and complete Table 3 with your answer.
