Forum Question:

The Forum includes several steps:

Identify a “different” research problem that would
be best studied using a non-probability sample.

Discuss why this research problem is best studied using a
non-probability sample, and what type of non-probability sample you would
likely use.

Find a peer-reviewed journal article (no more than five
years old) related to that research problem.

Discuss the sampling strategy/process used in the
article. What details are included, and
what information regarding the sampling was ignored?

Instructions for all Forums:

Each week, learners will post one initial post per
week. This post must demonstrate
comprehension of the course materials, the ability to apply that knowledge in
the real world. Learners will engage
with the instructor and peers throughout the learning week. To motivate engaged discussion, posts are
expected to be on time with regular interaction throughout the week. All posts should demonstrate college level
writing skills. To promote vibrant discussion as we would in a face to face
classroom, formatted citations and references are not required. Quotes should not be used at all, or used
sparingly. If you quote a source
quotation marks should be used and an APA formatted citation and reference
provided.

Reliability and validity are both very important in psychology. They help to ensure that an experiment is credible and can be used in Psychology. Reliability is important to make sure something can be replicated and that the findings will be the same if the experiment was done again. Validity ensures that an experiment can be generalised (external validity) and that it measures what it sets out to measure. To explain the importance of both reliability and validity I am going to write about the affect they have on the classification and diagnosis of depression.
