What is the relationship between Hypothesis and Variables?
A hypothesis is a testable statement or prediction about the relationship between variables in a research study. Variables are the elements that can change or vary, typically classified as independent (manipulated) and dependent (measured). The hypothesis often posits how changes in the independent variable will affect the dependent variable, guiding the research design and experimentation. Thus, the relationship between a hypothesis and variables is foundational for empirical investigation and analysis.
Define and differentiate between endogenous and exogenous variables?
The endogenous variables value is established by the conditions of the other variables in the structure. The exogenous variables value in independent of the conditions of the other variables in the structure. The difference between the endogenous and exogenous variables is the endogenous depends solely on the structure and the exogenous depend on outside elements.
What is descriptive investigation?
a descriptive investigation is a scientific ivestigation that collects data which measure or decribe objects or events. it collects qualitative & quantitative data. it includes a question, but no hypothesis ; no variables are manipulated .
What is the major difference between a mathematical model and an econometric model?
Mathematical model is exact in nature.it has Beta zero and Beta one and no stochastic or disturbance variables. Econometric model represents omitted variable, error in measurement and stochastic variables.
What is the difference between a manipulated and responding variable?
Manipulated variables are also known as independent variables. These are the variable which you change in an investigation. Plotted on the x axis.
How are difference from independent variables?
Constants stays the same independent variables is the variable that is being manipulated
What is the difference between manipulated variables and controlled variables?
They are the same. These are names for the variables in an experiment that are controlled by the experimenter, as opposed to the output variables, the results you collect at the end of the experiment Hope this helped!
3 types of variables?
controlled,manipulated,responding variables
How many manipulated variables can you have in an experiment?
1
What is the relationship in which the ratio of the manipulated variables and the responding variables is constant?
Direct Proportion
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
What do you call individual differences in things like values ethnic backgrounds age and the like?
Variables
How can an experiment that disproves hypothesis be useful?
by the variables. The variables are manipulated and responding. the manipulated ones are the one that is changed in the experiment. the responding variable is the one who is expected to change.
How can AN EXPERIMENT that disproves a hypothesis be used?
by the variables. The variables are manipulated and responding. the manipulated ones are the one that is changed in the experiment. the responding variable is the one who is expected to change.
How are constant variables different from independent variables?
Constants stays the same independent variables is the variable that is being manipulated
What are the 3 variables in science?
dependent variable; this is the factor in a experiment that when manipulated by independent variables it changes. it is also known as a controlled variable independent variables or manipulated variable; the factor in a experiment that is deliberately manipulated responding variable; the factor you have to measure to get the results or you will not know the value of the variable
