Direct control : a control that is directly imposed upon the manufacturing, pricing, and distribution of specific goods in contrast with an indirect or general control (such as a credit and fiscal policy) that affects the economy in its entirety and specific goods only indirectly.

What are some way to control extraneous variables?
Extraneous variables can be controlled through various methods, including random assignment, which ensures that participants are evenly distributed across different groups, minimizing bias. Standardizing procedures, such as maintaining consistent environments and instructions for all participants, helps reduce variability. Additionally, researchers can use control groups to compare results and statistical techniques to account for potential confounding factors. Lastly, pre-screening participants to match them on key characteristics can also help mitigate the influence of extraneous variables.
What essential characteristics distinguish a true experiments from other research designs?
True experiments are distinguished by three essential characteristics: random assignment, manipulation of an independent variable, and control over extraneous variables. Random assignment ensures that participants are evenly distributed across experimental conditions, minimizing biases. The manipulation of an independent variable allows researchers to observe its effect on a dependent variable, establishing cause-and-effect relationships. Additionally, control measures, such as using control groups or standardized procedures, help isolate the impact of the independent variable from other influencing factors.
What are the extraneous factors for business?
There are an endless array of both internal and external factors that can have either a positive or negative affect on business operations. External factors would include changes in the economy, government regulation, war, weather (i.e. hurricanes, flooding, etc.), competition and market changes, among others. Usually external factors are beyond the control of management.
In an experiment I is the control variable M is the response variable and amp N and amp P are extraneous factors. The specific units of are referred to as the treatments of the experiment.?
In an experiment, the control variable (I) remains constant to provide a baseline for comparison, while the response variable (M) is what is measured to assess the effects of the treatments. Extraneous factors (N and P) are variables that could influence the outcome but are not the focus of the study, and they need to be controlled to avoid confounding results. The specific units of measurement applied to the treatments are essential for analyzing how changes in the independent variable (not mentioned here) affect the response variable.
What are extrenous variables?
Extraneous variables are factors or conditions that are not the primary focus of a study but can influence the outcome of an experiment or research. They can introduce noise or bias, potentially skewing results and leading to incorrect conclusions. Researchers aim to control or account for these variables to ensure that the effects observed are truly due to the independent variable being studied. Proper experimental design helps minimize the impact of extraneous variables.
How do researchers control for factors that could influence a dependent variable?
Researchers control for factors that could influence a dependent variable by using various methods such as randomization, matching, statistical analysis, and experimental design. They may also use control groups, blinding techniques, and stratification to minimize the impact of extraneous variables on the dependent variable. By carefully designing and conducting experiments, researchers can isolate the effects of the independent variable on the dependent variable.

What are the 4 extraneous variables?
Extraneous variables are factors other than the independent variable that can influence the dependent variable, potentially skewing results. The four common types of extraneous variables include: Participant variables (individual differences between subjects, such as age or intelligence) Situational variables (environmental factors like temperature or time of day) Measurement variables (inconsistencies in how data is collected or measured) Confounding variables (factors that are related to both the independent and dependent variables, leading to false conclusions). Controlling these variables is crucial for ensuring the validity of research findings.
