Identify the appropriate test to use for the following scenario:

In a study of memory development, researchers selected pictures that could be classified into one of five categories (food, clothes, toys, furniture, animals). The pictures were presented in a random order to eight 4-year-olds and eight 5-year-olds, who were asked to memorize the pictures. The researchers used the order in which the pictures were recalled to obtain a clustering score for each child. A score of 1 meant that the pictures were not clustered by category at all during recall; whereas a score of 10 reflected perfect clustering of objects during recall (for example, all foods recalled first, then all animals, then all toys, etc.).

Using alpha = .05, determine whether or not the children of different age groups differed in terms of clustering in memory.
