To determine whether Mateo's sample of hiking trails is likely to be biased, we need to consider a few factors:
1. **Equal Number of Trails in Each County**: If each county has the same number of hiking trails and Mateo explores 2 trails from each county, this gives a balanced representation of trails across the counties. This is a positive aspect in terms of avoiding bias because he is not favoring one county over another.
2. **Sample Size**: Depending on the total number of counties and trails in the state, the sample size may still be relatively small. If there are many counties and trails in total, exploring only 2 trails per county might not capture the full diversity and characteristics of the hiking trails available.
3. **Trail Selection**: It is also important to consider how Mateo selects the 2 trails from each county. If he chooses them randomly, the sample is more likely to be representative. However, if he is choosing based on convenience or preference, this could introduce bias.
4. **Diversity of Trails**: Even if there are equal numbers of trails in each county, there might be differences in trail types (e.g., difficulty, scenery, length) within counties that are not being captured. If the 2 trails he selects from each county are not representative of the variety available, it may lead to biased conclusions about the hiking trails in the state.
Overall, while exploring 2 trails from each county does help to mitigate bias related to geographic representation, potential bias could still arise depending on the selection method and the diversity of the trails themselves. Therefore, while this approach is better than a random selection from the entire state without regard to counties, it is necessary to consider the overall sample size and selection process to fully assess the likelihood of bias.
