What is the difference between factor analysis with multidimensional scaling?

Multidimensional scaling (MDS):
Is a family of distance and scalar-product (factor) and other conjoint models. It re-scales a set of dis/similarity data into distances and produces the low-dimensional configuration that generated them.
Factor Analysis / Principal Components Analysis (FA/PCA), by contrast:
PCA is the full reduction of set of scalar-products to a new orthogonal set of spanning dimensions (components);
FA is a dimension-reducing model (properly containing communalities and not 1 in diagonal) to orthogonal or oblique dimensions (factors).
In general usage, PCA and FA are primarily dimensional and use interval-level data, whereas MDS usually uses an ordinal (non-metric) transformation of the data producing a spatial configuration where dimensions are arbitrary.

Define multivariate analysis?
Multivariate is the study of random variables which are multidimensional. Multivariate study is based on the statistical principle of multivariate statistics, which involves observation and analysis of more than one statistical variable at a time. In design and analysis, the technique is used to perform trade studies across multiple dimensions while taking into account the effects of all variables on the responses of interest.Multivariate study in MarketingStatistical procedure used in market research where more than one variable is analyzed at the same time. The goal of multivariate study is to identify statistical relationships between the variables, such as the relationship of home and family, or to gauge the dependence of the variables on each other through techniques such as conjoint-analysisor multidimensional scaling. Multivariate study in Dental:A set of techniques used when variation in several variables has to be studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables.Multivariate study in http://www.answers.com/library/Sports%20Science%20and%20Medicine-cid-9961188A statistical technique in which several dependent variables are analyzed simultaneously. For example, in a study of muscle strength, data may be collected on the age, type of training, and sex of the subjects being studied. In multivariate analysis, the effect of each of these variables can be examined, and also the interaction between them.
The effects of scaling are beneficial to swimmers who are relatively?
The answer is Large or Larger.
What is the importance of scaling a bar graph?
scaling a bar graph can be used for two reasons, to jump past a large group of numbers unused (say the bar graph goes from 1-1000 but none of the data starts below 500) Scaling can be important to emphasize a difference in numbers too, suppose item a is at 700, item b is at 850, and item c is at 1000. if your bar graph jumps from 1 to 500 and then goes up in increments of 100, it can make 700 look like its far less than 850 or 1000. this is usually a business tactic done to impress board members when presenting lackluster numbers.
Why do you use a broken bar graph?
A broken bar graph is used when one value, or a few values, goes up very high. Instead of scaling everything down, the abnormally high value is indicated with the broken bar graph. Of course, a number also has to be indicated, so that anybody who reads the bar graph can find out what the number actually is.
What is the difference between multidimensional and dimensional scaling?
The difference between multidimensional and dimensional scaling is in terms of relationship between physical characteristic and dimension. In the case of multidimensional scaling, each dimension can be connected to 2 or more physical characteristics, unlike dimensional scaling..

What is nonlinear scale?
Nonlinear scaling is a scaling where the difference between each major unit of measure is not the same. For example, see logarithmic scale.
