Identify the sampling method & explain selection of participants or relevant sample - known population, characteristic selection strategy describe and justify the sampling method and minimum sample size quantitative studies include probabilistic selection approach and of supporting power analysis for statistical significance of responses. When determining a minimum sample size, consider sampling error, represented to this, & assumptions of proposed statistical test. Describe how existing data were originally collected and for what purpose describe how participants were selected. Such as email lists from professional organization must be described. Sampling procedures - random, random stratified, convenience must be described in sufficient details of the process could theoretically be replicated. Materials/Instruments describe the source data and how the data were originally collected and for what purpose along with information regarding validity and reliability. Published instruments - adequately describe constructs measured, coding system, psychometric properties, including indices of reliability and validity - include as such in appendix if possible or include sample items materials including survey/instruments to study/adequately describe the development process and final product include an appendix. Note instruments self-development are strongly discouraged, appropriate existing validated instrument is not located, development process and tests for an instrument and construct reliability and validity must be described in detail within chapter 3 description of data sources
