SPSS Partial Vinous Sample - Research Proposal Example

1. Title To find out if wine tasting can efficiently be accomplished by people who have received short term learning experience as opposed to highly experienced people. 2. The last paragraph of the introduction This study aimed at establishing whether there is need to take years of learning so as for one to become proficient in identifying wines or wine testing is a skill which can be simply be learned within a short span of time of about two days. The hypotheses of the study was HO There is no difference in level of proficiency of wine identification for expert wine testers and novice testers H1 Expert wine testers will show high proficiency than the novice testers Methodology In this research there were a total of 60 participants with 30 belonging to expert group and the other 30 were in the novice group. All the 60 participants tested the 18 sample that were provided, with the samples being provided separately in small glasses of 1 ounce. The 18 samples were grouped in three with each set corresponding to a different variety of wine including Pinot Noir, Cabernet Sauvignon and Merlot. The procedure involved the participants tasting the three samples in the first set of 1 ounce samples and then moving to the next set of samples up to the time they were through with the six sets. In each of the set that were tested two came from the same wine bottle (the wine are from the same grape or the same grape combination) and the third sample came from a bottle that has the same type of wine as that of the first two samples but the vines used in this wine differed from those of the two (the wine was of different brand). The participants were expected two single out the two identical wines that had come from the same bottle by use of aroma and flavor cues. There was partial randomization of the sets for all the participants with the 1 ounce sample glasses being simply labeled as A, B and C. The testers were to rinse their mouths with water after going through each set and they were to avoid swallowing the samples as much as possible. The participants were to spit the tested wine on the bowl which had been provided to them. As away of ensuring that participants only used chemosensory faculties comprising of smell, taste and trigeminal, the participants were blindfolded when tasting the samples. This precaution was taken so as to avoid the possibility that the choices made by participants could be influenced by visual cues like the participants matching the two red wines that could be of identical shades. The score for each of the tests was given as a correct judgment coded as 1 or incorrect judgment whose code was given as a 0. The experts went through the tasting process on a Saturday night after they had a relaxed social dinner that was part of the program of the International Wine Symposium, which to place in a Sydney hotel. On the other hand the novice group did their tasting late on Sunday afternoon after they had just completed a wine tasting course. In this novice group the tasting was considered as being part of skills that would determine the final grade they would receive which could be a credit, a distinction or a high distinction, with fails and passes being omitted from the grading system. 4. The entire Results section Independent sample t-test was found to be the most appropriate tool to be used in investigating if there was a difference in scores of for wine testing proficiency for expert testers and for novice testers. The results obtained is test set 1 indicated that mean for experts .8889(SD=0.32338) and the mean for novice 0.7222(SD=0.46089) but the difference was not statistically significant t(18)=- 1.256, p>0.05. Set 2 indicated that the mean for experts 0.1111(SD=0.32338) and the mean for novice 0.6111(0.50163) with the difference being statistically significant t (18) = -3.554, p Read More
