ANSWERS) |ALREADY GRADED A+| ||PROFESSOR VERIFIED||
||BRANDNEW!!!||
What are some assumptions that ANOVA makes? - ANSWER-1)
The variances on "n" samples are similar
2) Populations are normally distributed
3) Independent errors
What is the Pseudomixed formula? - ANSWER-F=MSw/MSj*w
In order to find Fisher's LSD: - ANSWER-There MUST be a
significant F-test
Why are reference standards important? - ANSWER-1) Anchor
concepts for panel
2) Are a translation device to the outside world
PCA is... - ANSWER-a type of multivariate data analyses
,2|Page
Length of loadings in a PCA= - ANSWER-Importance of loadings
in explaining variation among samples
Problem with PCA: - ANSWER-Can't determine statistically
significant differnces
PC1= - ANSWER-Explains the maximum variance in data as a
linear combination of the original data
PC2= - ANSWER-Explains the remaining variance which is
uncorrelated to PC1
Name 2 types of PCA plots and what they do: - ANSWER-1)
Score plot: for the wines and how they are interpreted regarding
attributes
2) Biplot: the corresponding attributes themselves with the lines
Name 2 requirements of PCA: - ANSWER-1) Must have more
samples than variables
,3|Page
2) Number of PCs extracted=Number of terms
Name 2 Rapid Sensory Techniques: - ANSWER-1) Napping (or
Projective Mapping)
2) Sorting
What is Napping? - ANSWER--Judges group wines using their
own criteria where wines they perceive to have similar attributes
are closer together.
-Measure the XY distance of the wine placements from the left of
the nap.
-Then creates MFA: Consensus Map (Dim1 vs Dim2)
What is Sorting? - ANSWER--Assessor sorts products in as many
groups as needed based on perceived similarity.
-Then creates a Sorting Map and uses ellipsoids/determines
amount of overlap.
, 4|Page
Comparing DA, Sorting and Napping: - ANSWER-1) DA=very
small ellipsoids, little overlap, more specific
2) Sorting=medium ellipsoids, some overlap
3) Napping= large ellipsoids, a lot of overlap
In Analytical sensory evaluation, we are interested in... -
ANSWER-Discrimination/Descriptive
In Consumer sensory evaluation, we are interested in... -
ANSWER-Preference
Name the 3 tests of Consumer sensory evaluations: - ANSWER-
1) Paired-preference
2) Preference ranking
3) Preference rating
Paired preference asks the question: - ANSWER-Which wine
does a specific segment of consumers (or all) PREFER over
another?
