Operational Definitions of Variables

XXX. Text…
Checklist:
☐ For quantitative and mixed methods studies, identify how each variable will be (proposal) or was (manuscript) used in the study. Use terminology that is appropriate for the selected statistical test (e.g., independent/dependent, predictor/criterion, mediator, moderator).
☐ Base the operational definitions on published research and valid and reliable instruments.
☐ Identify the specific instrument that will be (proposal) or was (manuscript) used to measure each variable.
☐ Describe the level of measurement of each variable (e.g., nominal, ordinal, interval, ratio), potential scores for each variable (e.g., the range [0–100] or levels [low, medium, high]), and data sources. If appropriate, identify what specific scores (e.g., subscale scores, total scores) will be (proposal) or were (manuscript) included in the analysis and how they will be (proposal) or were (manuscript) derived (e.g., calculating the sum, difference, average).

Population and Sample
Begin writing here…
Checklist:
☐ Describe the population, including the estimated size and relevant characteristics.
☐ Explain why the population is appropriate, given the study problem, purpose, and research questions.
☐ Describe the sample that will be (proposal) or was (manuscript) obtained.
☐ Explain why the sample is appropriate, given the study problem, purpose, and research questions.
☐ Explain how the sampling guidelines that are associated with the chosen methodology and design will be (proposal) or were (manuscript) followed. For qualitative studies, evidence must be presented that saturation will be (proposal) or was (manuscript) reached. For quantitative studies, a power analysis must be reported to include the parameters (e.g., effect size, alpha, beta, number of groups) that were included, and evidence must be presented that the minimum required sample size will be (proposal) or was (manuscript) reached.
☐ Describe how the participants will be (proposal) or were (manuscript) recruited (e.g., email lists from professional organizations, flyers) and/or the data will be (proposal) or were (manuscript) obtained (e.g., archived data, public records) with sufficient detail that the study could be replicated.

These are the two sections that i’m having problems writing. i have attached the layout of what needs to be in these sections. This is a mixed method methodology. I also have attached the chapter 3 with the sections highlighted in blue. Everything in the checklist for the population and sample and Operational Definitions of Variables needs to be in the sections.
