A regression analysis was performed to assess the impact of the perception of risk (credit card information theft, identity theft, etc.) on the frequency of online shopping. The estimated slope of the regression line of frequency of shopping versus level of perceived risk was found to be – 0.233 and the standard error was 0.055. The sample size was 72.
