Answer 1

Answer:

Collins sampling method is the most effective.

Explanation:

There are a few reasons for this.

1. A much greater population of results

2. The people surveyed were chosen randomly so give a better insight into the population over all.

The second sampling method is a bit flawed in that it asks only 25 people, and these 25 people were sat near him and so may have similar interests therefore providing a degree of skew.
