what does Multivariate analysis mean?
86577
Multivariate analysis is a statistical technique to examine the effect of many variables on a single outcome.  For example, if you were studying what factors go into the price of a house, you might collect data about location, age of the house, and size of the house.  You could then perform a multivariate analysis to determine the relative contribution of each of those factors to the price of the home.

In short, no.\n\nAs a science, chemistry is usually separated into four main categories: organic, inorganic, physical, and analytical.  Analytical chemistry deals with detection, structural elucidation of chemical compounds, and instrumentation.  \n\nA chemical analysis is used to refer to a battery of tests that are performed on a given sample.

Policy analysis is the systematic evaluation of alternative means of achieving social goals. It is frequently deployed in the public sector but is equally applicable to other kinds of organizations. Most policy analysts have graduated from public policy school.\n\nPolicy analysis refers to the analysis of existing or prospective policies with the intention of improving social welfare. One common methodology is to define the problem and evaluation criteria; identify all alternatives; evaluate them; and recommend the best policy option.\n\nPolicy analysis differs from program evaluation in that it attempts to evaluate changes to policies and programs rather than evaluating their current performance. Policy analysts can come from many backgrounds including sociology, psychology, economics, law, political science, public policy, social work and public administration.

I believe this means, first of all, to write up the statistics in kind of an essay (textual) rather than tabular format. In other words, describe what the data in the statistics represents, give the all-around total numbers, and then using the demographic information-age, sex, ethnicity, socio-economic status-whatever you have, break down the numbers from the totals showing how they relate to and between the demographic sub-groups.

Ishiwara analysis is the analysis of the root causes of problems like late deliveries, defects in products etc. \n\nPareto analysis is a set of tools for making decisions. It is basically the idea that 20 % of the causes are responsible for 80% of the effect. It can also be used to try to ferret out the causes of failures.

How you use statistical tools to analyze your data depends entirely on what kind of data you have and the questions you are trying to answer with your data.  Some kinds of data lend themselves to descriptive analysis, in which you summarize your findings with means, medians, standard deviations, etc.  Other data are suitable for formal hypothesis testing, which calls for the application of statistical tools such as t-tests, analysis of variance, linear regression, multiple regression, proportional hazards modeling, life table analysis, etc.  Ideally, the preparatory phase of a research project would include a consultation with someone familiar with biostatistics before the data are ever collected.\n\nHowever, you can make a start by going to the following website:\n\nhttp://en.wikipedia.org/wiki/Statistics\n\nYou will learn a lot in a short period of time by going there.  But be careful!  Application of statistical tools in biomedical research is not a cookbook operation.  You would be well advised to consult with someone knowledgeable, who can inspect your data and offer advice about how to analyze them.  Such a person can also help you interpret the results of any statistical testing you do.  This is not always straightforward; misinterpretation of data and their analysis will lead to failure to get your papers published, at best, or worse, the misleading of the medical community and the general public about potentially serious issues.

In aerospace, it's someone who performs a structural or thermal analysis on a potential design.  This is different from a design engineer, who will design the hardware, circuit, etc in the first place.  Analyst doesn't do the design, just verifies that it will work.

Fourier analysis is a mathematical technique that has application in a lot of fields.  It's often used for retrieving meaningful data from statistical "noise", for instance..  it also shows up in antenna and filter design, signal analysis, and many other areas.

multicenter study is a study conducted at more than one distinct center where the data collected from these centers are intended to be analyzed as a whole. Unlike a single site study, a multicenter trial is much more complicated.

Qualitative analysis answers the question what substances or elements are within a sample. Quantitative analysis answers the question how much of these substances are within the sample.\n\nIn both cases, a negative answer means "we didn't find anything using the methods we had", not "there isn't anything of this substance inside".

# A statistical measure used in computing the correlation coefficient between two variables; the covariance is the mean of (x- x(bar))(yy(bar)) over all pairs of values for the variables x and y, where x(bar) is the mean of the x values and y(bar) is the mean of the y values. A statistical value measuring the simultaneous deviations of x and y variables from their means.\nhttp://helios.bto.ed.ac.uk/bto/glossary/c2.htm\n\n# A measure of the relation between two variables. The correlation coefficient is equal to the covariance of x and y divided by the product of the standard deviation of x and the standard deviation of y.\nhttp://www.indiainfoline.com/bisc/accc.html\n\nfor the formula, you can refer to this site - \nhttp://en.wikipedia.org/wiki/Covariance

An odds ratio that was computed using multiple regression analysis, therefore "adjusted" for more than one independent variable, is considered an adjusted odds ratio.

Depends on what you are analyzing.  Matrix algebra is used extensively in communications and signal processing applications.  Not very much, though, in financial applications.

c.\n\nIn probability theory and statistics, the coefficient of variation (CV) is a measure of dispersion of a probability distribution. It is defined as the ratio of the standard deviation to the mean
