If a researcher is constructing an APA-style correlation matrix for exactly three variables (working memory, executive function, and age) and follows all formatting conventions to avoid redundancy and trivial values, what is the exact number of Pearson's values that will be printed in the table, and in which section of the table will they be located?
Question: If a researcher is constructing an APA-style correlation matrix for exactly three variables (working memory, executive function, and age) and follows all formatting conventions to avoid redundancy and trivial values, what is the exact number of Pearson's values that will be printed in the table, and in which section of the table will they be located?
Sample answer: Exactly 3 Pearson's values will be printed in the table. They will be located in the bottom half of the matrix, below the diagonal dashes.
Key points:
- Identifies that exactly 3 Pearson's coefficients will be displayed.
- Specifies that the coefficients are located in the bottom half of the matrix.
Rubric: The answer must state that exactly 3 Pearson's values are displayed and that they are positioned in the bottom half (or lower-left triangle) of the matrix.
