The research objective for task 3 was to use an ANOVA test to compare the average consumer familiarity of the Big W brand and its competitor Kmart among multiple annual income groups. Consumer brand familiarity was measured using sample data collected from the survey question 'Rate your familiarity with following stores below...' to determine whether there was a significant difference between the brand familiarity of the following four levels of household income groups: less than $50,000, more than $50,000/less than $100,000, more than $100,000/less than $150,000, and more than $150,000. The first ANOVA test analysis focused on Big W, and the second on Kmart. The sample size of the lowest income group was 25, the second income group was 60, the third income group was 175, and the highest income group was 100. A one-way ANOVA test was utilised to analyse Big W's consumer familiarity in relation to consumers' annual income levels. The ANOVA test showed that brand familiarity was significantly different among different levels of income earners, and that lower income households were more familiar with the Big W brand due to the importance of lower price and discounts. From the 0.000 p-value <0.05, the null hypothesis can be rejected, and the alternative can be accepted (Ha: 1234 *). This means that there were one or more independent variables or income groups that exhibit significantly different means
