The sample is biased because sample size is too small. So option (1) she should have asked more people is the correct answer.
Sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others. Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others.
For the given situation,
Sample size = 20
Here Matilda have surveyed only 20 people. Since it is a less value, the sample is biased.
We could not take as the population suggestion with the suggestion of only seven people.
To know the population's liking's, Matilda should have asked more people in the street if they would like to discuss what they want to do during the summer break asked more number of people in the population.
Hence we can conclude that the sample is biased because sample size is too small. So option (1) she should have asked more people is the correct answer.
