We broke it down from men and woman and standardized each one with a number in order to complete in Excel. The descriptive statistics will be analyzed below. In Appendix A through C will show the different ways the sex was seen. Brand Variable two we utilized the brand that the customer was choosing. Brand A and Brand B were both given a value in order to see how a customer would choose and could be broken down into our data charts to be summarized. In the Appendix's below data will be shown. Descriptive Statistic Interpretation DESCRIPTIVE STATISTICS 3 Sex Throughout the survey we had more males surveyed then females. This was by about twenty plus people which played a factor in how the first metric was seen. The mean and median could have been skewed because of the value of zero being utilized. Brand The choice of brands was very different then the numbers we saw for the first metric. The brand was a difference of six individuals who choose brand B over brand A. Although some metrics were very similar and put the two values very close and similar. The brand of choice from our surveyors was what we were watching and trying to determine which brand would be chosen over the other.
