What is Snowball Sampling?

• Snowball Sampling is a technique used in winter sports to measure snow depth

• Snowball Sampling is a non-probability sampling technique where existing study subjects recruit future subjects from among their acquaintances.

• Snowball Sampling is a method of collecting data by throwing snowballs at random people

• Snowball Sampling is a statistical method for predicting snowfall in a region

Explain Convenience Sampling.

• Convenience sampling is a non-probability sampling technique where subjects are selected based on their easy availability and proximity to the researcher.

• Convenience sampling is a technique used only in laboratory settings.

• Convenience sampling involves selecting subjects randomly from a population.

• Convenience sampling ensures a representative sample of the population.

Define Purposive Sampling.

• Purposive sampling is a non-probability sampling technique where researchers select participants based on specific characteristics or qualities relevant to the research purpose.

• Purposive sampling is a technique used to ensure a representative sample of the population.

• Purposive sampling involves selecting participants based on their age and gender only.

• Purposive sampling is a random sampling technique where participants are chosen without any specific criteria.

How does Quota Sampling work?

• Quota Sampling involves selecting participants based on their willingness to participate.

• Quota Sampling works by selecting participants based on predetermined quotas for different subgroups within the population.

• Quota Sampling involves selecting participants randomly from the population.

• Quota Sampling requires selecting only participants from a specific age group.

What are the advantages of Snowball Sampling?

• Snowball Sampling is time-consuming

• Snowball Sampling is advantageous because it helps in identifying hidden populations, is cost-effective, and provides access to hard-to-reach individuals or groups.

• Snowball Sampling leads to biased results

• Snowball Sampling is only suitable for large populations

What are the limitations of Convenience Sampling?

• Convenience Sampling ensures representative samples

• Convenience Sampling eliminates selection bias

• Convenience Sampling may lead to selection bias and lacks generalizability.

• Convenience Sampling is cost-effective

Give an example where Purposive Sampling would be appropriate.

• Study on the experiences of female entrepreneurs in a specific region

• Investigation into the effectiveness of a new medication for heart disease

• Research on the impact of climate change on marine life

• Study on the eating habits of teenagers in a specific region

Discuss the challenges of implementing Quota Sampling.

• Minimal management required

• Not defining quotas clearly

• Using random sampling instead

• The challenges of implementing Quota Sampling include accurate subgroup representation, potential bias, defining quotas, and resource-intensive management.

Compare and contrast Snowball Sampling and Purposive Sampling.

• Snowball Sampling involves selecting participants randomly, while Purposive Sampling involves selecting participants based on referrals.

• Snowball Sampling is based on referrals from initial participants, while Purposive Sampling selects participants based on specific criteria.

• Snowball Sampling selects participants based on specific criteria, while Purposive Sampling is based on referrals from initial participants.

• Snowball Sampling is a method used in qualitative research, while Purposive Sampling is a method used in quantitative research.

Why is Convenience Sampling often considered less reliable?

• Convenience Sampling ensures a representative sample of the population.

• Convenience Sampling can introduce bias due to the non-random selection of participants.

• Convenience Sampling eliminates the need for random selection.

• Convenience Sampling reduces the likelihood of bias in research.
