What does applications mean in a science project with plants?
It is when you apply your data to the real world, and how it can help you in the real world.
Give an example of quantitative data?
Quantitative data deals with numbers. It is data that can be measured. An example of this is: 51% of the world's population is female.
Population data of tigers in the world?
A good estimate is around 5000.
What is the population of llamas?
There is no exact data as to how many llamas are in the world. The population of llamas is most likely in the millions.
Why weather forecasting has improved?
Weather forecasters have better technology now. They can use computer models to help for example. There is also more satellites. They have more experience and knowledge that they can apply to forecasting. It is easier for forecasters to work together and gather and share data to have a more accurate forecast.Weather forecasters have better technology now.

What is a Data Models?
A Data Model is a way to organize the data that you have, it gets the information and using a set of rules it makes sure that the data is good quality for you to use. Data Models are normally used to get data in, merge already existing data and to get data out. Data Models are also used for people that are working on the same project but in different groups to communicate. There are multiple different Data Models, each one has its own befits and problems through each one is designed for a certain job.
What will be the climate in 2012 related to global warming?
That would be impossible to answer. The problem is that most of "global warming" is dependent on computer models of how the climate works, using all kinds of current data to predict what the future climate will be. The problem is that the models are badly flawed; given all known data for everything before last year, the models are incapable of predicting the current conditions. The models say that the world should be warming; the data doesn't show that.
Is the data is sample or population?
Data is neither sample nor population. Data are collected for attributes. These can be for a sample or a population.
What is the difference between econometric and mathematical economics?
Econometrics analyzes real-world data. Theory writes mathematical models.
How data will store in DBMS?
Databases store data using any of the robust data structures for efficient management of data. They can use any of the record based logical models to represent the data. Hierarchical, Network or Relational data models.
Define data models and list different types of data models?
A data model is a collection of concepts that can be used to describe the structure of a database and provides the necessary means to achieve this abstraction whereas structure of a database means the data types,relationships and constraints that should hold on the data. Data model are divided into three different groups they are 1)object based logical model 2)record based logical models 3)physical models Types: Entity-Relationship (E-R) Data Model Object-Oriented Data Model Physical Data Model functional data model
