Research Methodology <br />Quantitative Research <br />In order to validate the findings and inferences of this project, HR2 <br />Research/Analytics used interactive voice/web surveys and in-person intercept <br />surveys. This supported the empirical findings with the hard data necessary to reach <br />the goals of this project. The proposed survey research design involved a random <br />total statistical sample. All persons who do not meet the survey criteria were screened <br />out of the survey. <br />Sampling Frame <br />The sampling frame involved a stratified probability sample of respondents living <br />within the zip code of City of Tukwila. The sampling frame for the intercept surveys <br />included 250 residents and 50 businesses or home owner's association (HOA) <br />directors for a total of 300 samples, an increase in the totals from previous years' <br />research. <br />The following table represents the sample sizes for the previous research project years <br />of 2011 through 2013, 2015 and 2017. <br />2011 <br />2012 <br />2013 <br />2015 <br />2017 <br />100 <br />100 <br />103 <br />105 <br />50 - Business <br />250- Residential <br />2017 Sam s lin ' Frame <br />Interactive Voice <br />and <br />Web Survey <br />Residential <br />250 <br />Residential respondents <br />living within zip code of <br />Tukwila <br />28 <br />
