Comfort & Overall Experience
Comfort & Cleanliness
One-Way ANOVA Compare means of variables using prototype as factor to find significance of differences Full analysis was done on 19 variables 19 variables listed earlier 17 prototypes
Food served timely Prototypes 6 and 8.X did well Protype 11 did poor in comparision You will notice in most the graphs there are prototypes better than others but if you look at the values you see it is a small gap. Here for example there is only a max difference of about 0.2 The blue line has no mathematical or numerical value. It was chosen to offset the top 2-3 points and the bottom 2-3 that were significantly different than most 5.A SP 7.X 8.X 5.AX 6.X 8.M
Comfort GOOD 8 9 10 12 7.X BAD 11 5.A SP 5.A 7.X 8.X 5.AX 6.X 8.M
Atmosphere GOOD 8 9 10 12 14 8.M BAD 11 SP 5.A 7.X 8.X 5.AX 6.X 8.M
Compare to similar overall GOOD 8 9 12 14 8.X BAD 11 7.X SP 5.A 7.X 8.X 5.AX 6.X 8.M
Overall GOOD 9 12 BAD 11 SP 5.A 7.X 8.X 8.M 5.AX 6.X
Conclusion Prototype 14 consistently scored higher than the rest Changed exterior and interior Newer look : Stone and perforated metal exterior accents; cook-off/ event pictures, toys and cars spotlighted inside 7 stores and 4078 entries
Conclusion Prototype 11 and 7.X consistently scored low 11 only has one restaurant 7.X is expanded 7; once again only a few 7.X may have scored low because of location and not prototype
Suggestion It appears that the prototype does not affect the comfort much Benchmarks may help to better separate the strong and weak prototypes Look at top 2 boxes of ratings instead of means
Suggestion With minor adjustments to staff, air, and table spacing comfort levels could improve More detailed questions on GSS or focus group may offer more insight
