Definition of Multivariate Multivariate: Multivariate refers to a dataset or analysis that considers more than one variable at a time. For example, in a multivariate analysis, you might examine the relationship between height and weight in order to understand how they are related. How is Multivariate used? Multivariate analysis is a collection of techniques used…
Definition of Modeling Modeling: Modeling is the process of creating a mathematical representation of a real world phenomenon. Modeling is a process of using past data to understand and predict future outcomes. It can involve creating mathematical models to represent relationships in the data, or using machine learning techniques to build models from data that…
Definition of Mode Mode: Mode is a statistical measure of the typical value of a data set. It is calculated by taking the sum of the data values and dividing by the number of data points. Mode is most useful when dealing with nominal data. How is Mode used? Mode is a central measure of…
Definition of Metadata Metadata: Metadata is data that describes other data. It can include information such as the date a file was created, the author of a document, or the keywords used to identify a piece of content. Metadata can be used to help organize and find information, and to track changes to data over…
Definition of Meta-analysis Meta-analysis: A meta-analysis is a literature review of qualitative and quantitative studies that have been published on a specific topic. The goal of a meta-analysis is to summarize the findings of these studies and to identify patterns in the data. How is Meta-analysis used? Meta-analysis is a statistical technique used to combine…
Definition of Measurement Measurement: A measurement is a quantifiable value that is assigned to a variable. Measurement is the process of quantifying a property of an object. How are Measurements used? Measurements play an important role in data science and machine learning. They are used to help quantify and compare models, features, and data points….
Definition of Mean Mean: Mean is a mathematical calculation used to calculate the average of a set of numbers. How is the Mean used? The Mean is a statistical measure used in data analysis and machine learning to evaluate the central tendency of a given set of numerical values. It is calculated by adding up…
Definition of Matrix Matrix: A matrix (plural matrices) is a rectangular array of numbers, symbols, or other objects. The individual items in a matrix are called its elements. Related: “The Matrix” is an awesome movie from 1999. How is a Matrix used? A matrix is an array of numbers or other data used in mathematics…
Definition of Mathematical Statistics Mathematical Statistics: Mathematical statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It also provides techniques for estimating properties of populations from samples. Mathematical statistics is distinguished from other statistical techniques in that it relies on mathematical theory as a foundation. What…
