What are some relationships that exist between variables?
Causation, correlation...
Uses bars to show the relationships between variables?
A Bar Graph!
How do you determine the relationships between the variables?
That's exactly what the equation tells you.
What are Advantages to Correlation study?
An advantage of using a correlational study is that it allows you to investigate variables that cannot be directly manipulated.
In 2x plus y what are the variables?
A variable is a number that isn't fixed, it can be anything. So in this situation x and y are the variables.
What variables are needed to investigate purification of water?
Time and temperature
What is explanatory reserch?
Explanatory research aims to explain the relationships between variables and phenomena by uncovering the underlying mechanisms and factors that influence outcomes. This type of research goes beyond describing a situation to understand why or how something occurs. It is often used to test hypotheses and establish causal relationships between variables.
How are variables used to show relationships?
Variable are used to show relationships by multiple ways.
Can an experiment that has several variables be used to explain theory?
Yes, an experiment with several variables can be used to test and provide evidence for a theory. By manipulating and controlling the variables, researchers can investigate the relationships between them and how they affect the outcomes, helping to support or refute theoretical predictions. However, it is essential to design the experiment carefully to ensure that the results are reliable and can contribute to a better understanding of the theory.
What is CROSS sectional study retrospective study?
A cross-sectional study is a type of observational research that analyzes data collected from a population at a single point in time to assess relationships between variables. In contrast, a retrospective study looks at past data to investigate possible links between exposure and outcome variables.
A situation in which variables lies?
an equation
What is associative research design?
Associative research design is a type of research methodology that aims to establish relationships between variables by studying the statistical associations between them. It does not imply causation, but rather shows the degree of relationship between variables. This design is commonly used in fields such as psychology, sociology, and medicine to investigate correlations and patterns.
What are two types of mathematical relationships that exist between different variables?
Direct or inverse relationships,that is a problem
What are some relationships that exist between variables?
Causation, correlation...
How many variables do you investigate in a controlled experiment?
There are complex models that allow researchers to study several variables if the experiment is carefully designed and very carefully carried out. These models can show whether a variety of variable interactions occur, and if that is your focus then these models are good. But the best experiments investigate a small number of variables, as few as one.
What are interfering variables?
An intervening variable is a hypothetical internal state that is used to explain relationships between observed variables
What is Research that is guided by a hypothesis called?
Research that is guided by a hypothesis is called hypothesis-driven research. It involves designing experiments and collecting data to test a specific hypothesis or theory. This type of research helps to systematically investigate and understand relationships between variables.
