Standard deviation: average measure from data and mean (square root of variance).How far the data is on average from the mean.
Solve: Find the variance and take the square root of it.
Coefficient of Variation: standard deviation of two sets of data. Shown as as a percentage and measures the variation side by side with the mean
Solve:: CV = standard deviation/ mean * 100
Counting numbers is discrete
Center and Variability:
Descriptive Measures: a single number thats comes from the sample data

Any marketing actions a firm takes today can change consumer’s brand awareness or brand image and have an indirect effect on the success of future marketing activities. For example; the frequent use of temporary price decreases as sales promotions may create or strengthen a “discount” association to the bran, with potentially adverse implications on customer loyalty and responses to future price changes or non-price-oriente marketing communication efforts. Marketers must actively manage brand

Cluster: A collection of data objects
similar (or related) to one another within the same group
dissimilar (or unrelated) to the objects in other groups
Cluster analysis (or clustering, data segmentation, …)
Finding similarities between data according to the
characteristics found in the data and grouping similar
data objects into clusters
Unsupervised learning: no predefined classes (i.e., learning
by observations vs. learning by examples: supervised)
Typical applications

New products and brand extensions:
New products are often vital to the long run success of a firm. When a firm introduces a new product, it has three choices for branding it:
It can develop a new brand, individually chosen for the new product.
It can apply one of its existing brands.
It can use a combination of a new brand and an existing brand.
A brand extension occurs when a firm uses an established brand name to introduce a new product. When a new brand is combined with an existing brand,

Vertex
A point where two or more straight lines meet.
Angle Addition Postulate
for any angle, the measure of the whole is equal to the sum of the measures of its non-overlapping parts
Angle Bisector
a ray that divides an angle into 2 congruent angles
Midpoint
a point that divides a segment into 2 congruent segments
Reflexive Property
A quantity is congruent (equal) to itself. a = a
Symmetric Property
If a = b, then b = a
Transitive Property
If a=b and b=c, then a=c
Complementary Angles
Two angles whose sum is
