A marine biologist conducted an ecological survey to investigate whether nesting site preference differs between two species of sea turtle. Over a nesting season, the biologist monitored a protected coastline and recorded the beach sector (Rocky Sector or Sandy Sector) chosen by each nesting female. The collected data is presented in the table below.
Table showing the nesting frequencies of Loggerhead and Green turtles across beach sectors
| Nesting Sector | Loggerhead Turtles | Green Turtles |
|---|---|---|
| Rocky Sector | 24 | 9 |
| Sandy Sector | 11 | 31 |
The biologist decided to use a Chi-square test to analyse the data from this study.
Explain one reason why a Chi-square test is the appropriate statistical test to use in this study.
