# Cross-Tabulations

*Case 2 · the third variable*

Does age influence the desire to travel and seek adventure?

Desire for international travel by age

| Desire for international travel | Age |  |
|------|------|------|
| Under 45 | 45 and over |  |
| yes | 50 % | 50 % |
| no | 50 % | 50 % |
| Total | 100 % | 100 % |
| Number of cases | 500 | 500 |

… by age and gender

| Desire for international travel | Male | Female |  |  |
|------|------|------|------|------|
| < 45 | ≥ 45 | < 45 | ≥ 45 |  |
| yes | 60 % | 40 % | 35 % | 65 % |
| no | 40 % | 60 % | 65 % | 35 % |
| Total | 100 % | 100 % | 100 % | 100 % |
| Number of cases | 300 | 300 | 200 | 200 |

Aggregated (50%/50%), age appears to play no role. Only when split by gender does it become clear: for men the desire to travel rises with age, for women it falls — a **hidden relationship** .
