Case Study: Mi Casa Front Porch Restaurant

Analysis of variance (ANOVA) is a process that is used to compare three or more population means at the same time (Donnelly, 2013). In this scenario, Mi Casa Front Porch restaurant is looking to better understand customer satisfaction levels. A student intern assisted Mario of the Mi Casa Front Porch restaurant with some data analysis from three different locations. Mario also recognized that there are two distinct customer types that frequent the three locations. Unfortunately, the student intern is unsure how to approach the analysis of all of the data that was gathered. I will assist the intern by designing an ANOVA and discuss the number of factors, treatments, and observations there are for the provided data. A two-way ANOVA is the process where a person can observe the simultaneous …show more content…
The locations (Factor A) have three levels, which are downtown Phoenix, North Scottsdale, and Glendale. The customers (Factor B) have two levels, which are cantina customers and restaurant customers. There are a total of six treatment groups or cells, because there are three levels in Factor A and two levels in Factor B (3 * 2 = 6). The six treatment groups or cells are the cantina customers at the downtown Phoenix, North Scottsdale, and Glendale locations and the restaurant customers at the downtown Phoenix, North Scottsdale, and Glendale locations. We do not have the exact number of observations for the two-way ANOVA, but it would be wise to start out with five observations per treatment group or cell. The cantina customers would have five observations per location and the restaurant customers would have five observations per location for a total of 30 observations. The two-way ANOVA gives us the unique ability to compare the locations to the customer types and the customer types to the locations. We would be testing to see if the average customer ratings between the two customer types differ among the three locations. Also, we would be testing to see if the
