Researchers conducted a study looking at the level of mathematical anxiety among university students. They developed a new assessment tool called the Maths Anxiety Index (MAI). Table 1 shows some of their initial findings.
| Student group | Mean MAI score (out of 50) |
|---|---|
| Mathematics undergraduates | 14.5 |
| Art History undergraduates | 38.2 |
Outline how these researchers could use a statistical test to establish the concurrent validity of their new Maths Anxiety Index (MAI).
