Understanding third perception about Internet privacy risks

The current study used a sample of the U.S Mturk respondents in November 2016. Mturk self-selected respondents to participate the survey. A respondent who completed the questionnaire received $3. Such compensation is common in survey research as a means to enhance response rates (Largent, Grady, Miller, & Wertheimer, 2012). The sample size of the current study was 613. According to prior statistical research, if continuous variables play primary roles in data analysis and the alpha level is set a priori at .05, level of acceptable error at 3%, and standard deviation of scale is 1.167 (7/6), the minimum recommended sample size is 118 using Cochran’s sample size formula (Kotrlik & Higgins, 2001). Survey scientists often increase the minimum sample size by 40% to 50% as compensation for the incomplete submissions (Fink, 1995; Salkind, 1997). In the current study, the size sample of 613 should provide satisfactory statistical power.
