What is the correct sampling technique to use when seeking students with learning disabilities by relying on special education coordinators to identify them?

Here's why:

• Purposive Sampling is a non-probability sampling method where the researcher deliberately selects participants based on specific characteristics or criteria relevant to the research question. In this scenario, the researcher is specifically seeking students with learning disabilities who are willing to share their experiences, and they are relying on special education coordinators to identify these specific individuals. This intentional selection based on expert judgment fits the definition of purposive sampling.

The other options are incorrect:

• Systematic Sampling involves selecting participants at regular intervals from a list.
• Snowball Sampling involves initial participants recruiting further participants from their network.
• Simple Random Sampling involves every member of the population having an equal chance of being selected, typically through a random process.

The correct option is Purposive Sampling.
