14.45 Winery websites.
As part of a study of British Columbia wineries, each of the 193 wineries were classified into one of three categories based on their website features. The Presence stage just had information about the winery. The Portals stage included order placement and online feedback. The Transactions Integration stage included direct payment or payment through a third party online. The researchers then compared the number of market integration features of each winery (for example, in-house touring, a wine shop, a restaurant, in-house wine tasting, gift shop, and so on). Here are the results:8
Stage | |||
Presence | 55 | 3.15 | 2.264 |
Portals | 77 | 4.75 | 2.097 |
Transactions | 61 | 4.62 | 2.346 |

(a) The Portals and Transactions stages seem to have higher integration features than the Presence stage. (b) An observational study. They are not imposing a treatment on the winery. (c) Yes, the largest is less than twice the smallest ; . (d) This shouldn’t be a problem because our inference is based on sample means, which will be approximately Normal given the sample sizes. (e) . There are significant differences in the number of market integration features of the wineries among those with different website stages.
