## Study Notes

### Types of Sampling Methods

• Haphazard (Convenience/Accidental) Sampling: Get cases in any manner that is convenient, introducing biases in the sample.
• Example: Studying the impact of social media on teenagers' mental health by interviewing the first 15 students available during lunch break at a local high school.
• Bias: Sample is biased towards students with strong opinions or those with free time during lunch break.

### Quota Sampling

• Quota Sampling: Get a preset number of cases in several predetermined categories that reflect the diversity of the population, using haphazard methods.
• Example: Studying consumer preferences regarding sustainable packaging in the food industry by dividing the population into subgroups based on age and gender, then interviewing 25 people from each age group.
• Bias: Sample is diverse, but does not guarantee statistical representation of the population as a whole.

### Purposive Sampling

• Purposive Sampling: Get all cases that fit a particular criteria, often used for in-depth investigation.
• Example: Studying the motivations and challenges faced by early adopters of electric vehicles by selecting participants who have owned and used an electric vehicle for at least one year.
• Bias: Allows for rich, detailed insights, but results may not be generalizable to all-electric vehicle owners or potential buyers.

### Snowball Sampling

• Snowball Sampling (Network, Chain Referral, Reputational): Get cases using referrals, creating networks represented by sociograms.
• Example: Exploring the living conditions, challenges, and coping mechanisms of undocumented immigrants in a particular city by making contact with local NGOs and then using referrals to expand the sample.
• Bias: Allows access to a hard-to-reach population, but may not be representative of the entire population.
