Research Methodology Concepts

Coach Sierra introduces research terms, explaining the systematic nature of research and the importance of research questions. She discusses hypotheses, variables, control groups, and different research types. The video covers literature reviews, sampling, validity, reliability, ethical considerations, and data analysis. It concludes with contact information for further learning.

• To receive the treatment

What type of data does quantitative research collect?

What does internal validity refer to?

• The ethical considerations of the study

• The extent to which a study measures what it claims to measure

• The consistency of the measurements

• The generalizability of the results

What is the role of the IRB in research?
