follows and recommends this question

Multivariate means more than 1 y=DV multivariable means more than 1 x=IV Because variate means RANDOM variable You can google all of this. to get full definitions but that's it

By default, the terms 'multivariate analysis' and 'multivariable analysis' are often used interchangeably in medical and health sciences researches. how ever, in real scenario they are used in differently.

Multivariable analysis is used for analysis with one outcome (dependent variable) and multiple independent (predictors or factors while Multivariate is used for the analysis with more than 1 outcome variables (eg, repeated measures) and multiple independent variables.

Dear Takele Gezahegn Demie

Multivariate statistics is a subdivision of statistics encompassing the simultaneous observation and analysis of more than one outcome variable. The application of multivariate statistics is multivariate analysis.

Multivariate statistics concerns understanding the different aims and background of each of the different forms of multivariate analysis, and how they relate to each other. The practical application of multivariate statistics to a particular problem may involve several types of univariate and multivariate analyses in order to understand the relationships between variables and their relevance to the problem being studied.

In addition, multivariate statistics is concerned with multivariate probability distributions, in terms of both

• how these can be used to represent the distributions of observed data;
• how they can be used as part of statistical inference, particularly where several different quantities are of interest to the same analysis.

Answer to your question

Certain types of problems involving multivariate data, for example simple linear regression and multiple regression, are not usually considered to be special cases of multivariate statistics because the analysis is dealt with by considering the (univariate) conditional distribution of a single outcome variable given the other variables. Therefore in 'multivariable analysis' each variable can be dealt with individually since they might be not correlated to each other. Whereas 'multivariate analysis' technically arise where there is correlation present between the variables.

I hope this helps

The term "multivariate" refers to multiple independent variables or numerous measurements of the same independent variable, while the term "multivariable" refers to numerous dependent variables but only one independent variable.

Thank you ALL for your time and help! I got it!

Dear Mauricio Lopez-Espejo,

Your answers seem opposite to others. I think you interchange Y with X.

Do you have any different ideas?

Please check the following article describing the differences:
