How does modeling differ from experimentation?
A prediction is somthing u guess .An experiment is somthing you do based off of a prediction
What do scientist use to visually represent the their data so that the relationship can be seen?
Graphs
What is the modeling of the phylogeny of a species?

What are the advantages and disadvantages of describing a relationship between variables in a writen report?
Advantages: You can collect the correct data in words rather than in numbers. Disadvantages: Sometimes you can't find all the data when it is written.
What tool do scientist used to create modelsanalyze data and show results?
Scientists use various tools to create models, analyze data, and present results, including software applications like MATLAB, R, and Python for data analysis and visualization. Additionally, simulation software such as COMSOL and ANSYS helps in modeling complex systems. Data visualization tools like Tableau and Excel aid in displaying results clearly. Together, these tools facilitate the understanding and communication of scientific findings.
What is entities database?
Entity means a specific thing in both database work and data modeling. An entity is data that can be classified, and has a relationship with other classified data, as in entities.
What type of job does data modeling?
One type of job that does data modeling involves web design and creating MySQL databases. To create a MySQL database one must have knowledge in data modeling.
Why does 1 equal 1?
Because equality is a reflexive relationship.
What are the typical application areas of supercomputers?
Environmental modeling Financial modeling Atomic explosion modeling. Cryptography Data processing for big data experiments such as BABA and CERN.
What is er model in dbms?
In software engineering, an Entity - Relationship model(ER model for short) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion. Diagrams created by this process are called entity-relationship diagrams or ER diagrams.learn more www.ngprakasam.hpage.com
What is the difference between explanatory and predictive modeling in data analysis?
Explanatory modeling focuses on understanding the relationships between variables, while predictive modeling aims to make accurate predictions based on data patterns.
What are some effective data modeling tools?
Data modeling tools are software components that organize extracted information from pre-existing data. Some effective tools are ProDesigner, ER/Studio and CA ERwin.

Importance of data modeling?
shows the importance of what your data holds to the people your trying too persuade
what is data modeling?
A data model is a conceptual frame work that outlines how data is structured, organized, and stored with in a database or information system. It defines relationships between different data types and specifies rules and constraints for data access and manipulation. Visual representations such as entity-relationship diagrams or UML diagrams, are often used to illustrate data model structures.
What does data vault modeling mean?
Data vault modeling is a method used for storing lots of historical data from multiple systems at any one time. It tracks where date has come from and where it is going without making any distinctions between good and better data.
What is entity in database?
Entitie are the principal data object about which information is to be collected. Entities are usually reognizable concepts,either concrete or abstract, such as: person,university,employees etc.
