# What are main outcome variables?

A dependent variable, also called an outcome variable, is**the result of the action of one or more independent variables**. It can also be defined as any outcome variable associated with some measure, such as a survey.

## What are the 3 types of variables in research?

An experimental inquiry typically has three main types of variables: an independent variable, a dependent variable and controlled variables. We will look at each of these three types of variables and how they are related to experimental inquiries involving plants.## What is the main predictor variable?

A predictor variable is used to predict a future outcome based on given circumstances. Other names for this variable include criterion variable and explanatory variable. Predictor variables are important when trying to estimate or extrapolate a future outcome based on information that is known.## What is an example of a primary outcome measure?

Examples of primary outcome include [difference in… or difference in change in…] blood pressure, recurrence of kidney stones, quality of life, pain score, death or albuminuria. The ideal primary outcome is important to all stakeholders – especially to patients.## What is the cause outcome variable?

While the independent variable is the “cause”, the dependent variable is the “effect” – or rather, the affected variable. In other words, the dependent variable is the variable that is assumed to change as a result of a change in the independent variable.## Independent,Dependent, and Control Variables

## What is an example of an outcome variable in statistics?

In the context of an experimental study, the dependent variable (also called outcome variable) is directly linked to the primary outcome of the study. For example, in a clinical trial on psoriasis, the PASI (psoriasis area severity index) would possibly be one dependent variable.## What does outcome variable mean in statistics?

Dependent and Independent VariablesAn independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

## What is a main outcome measure?

The primary outcome measure is the outcome that an investigator considers to be the most important among the many outcomes that are to be examined in the study.## What are two examples of outcome measures?

Outcome measures reflect the impact of the health care service or intervention on the health status of patients. For example: The percentage of patients who died as a result of surgery (surgical mortality rates). The rate of surgical complications or hospital-acquired infections.## What are the three types of outcome measure?

Outcome measures that we use in clinical practice are divided into four categories:

- Self-report measures.
- Performance-based measures.
- Observer-reported measures.
- Clinician-reported measures.

## What is the outcome variable in research?

A dependent variable, also called an outcome variable, is the result of the action of one or more independent variables. It can also be defined as any outcome variable associated with some measure, such as a survey.## What is an alternate name for an outcome variable?

Dependent variables are often referred to by a number of synonyms including response variable, measured variable, explained variable, outcome variable, experimental variable, and output variable. Many of these synonyms are used extensively in statistics.## What is a main dependent variable?

Dependent variables:Dependent variables depend on other variables. For example, if someone was studying the effects of pollution on asthma, the incidence of asthma would be the dependent variable.

## What are the two main variables in research?

Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect.## Is the independent variable the outcome?

Independent variables are what we expect will influence dependent variables. A dependent variable is what happens as a result of the independent variable. Generally, the dependent variable is the disease or outcome of interest for the study, and the independent variables are the factors that may influence the outcome.## How do you identify variables?

Variables are found in the hypothesis or research question. In a hypothesis, you can see how variables operate in a research study. To identify Independent research variables, look for items in your research question or hypothesis that manipulates, causes or influences something or a reaction.## How do you write an outcome measure?

Tips for Writing Outcomes

- Be sure that outcomes are precise, specific and clear statements that tell the intended accomplishments.
- Each goal should have two to three outcomes to support it.
- Using Bloom's Taxonomy can help with determining the level of engagement for outcomes.

## What types of outcomes are there?

Types of Outcomes

- Impossible outcome.
- Unlikely or least likely outcome.
- Equally likely outcomes.
- Most likely outcome.
- Certain outcome.

## What are the different types of outcome data?

In the Outcomes domain, outcome measures are grouped into five main categories: survival, clinical response or status, events of interest, patient-reported, and resource utilization. These categories represent both final outcomes, such as mortality, as well as intermediate outcomes, such as clinical response.## What is an example of an outcome variable in research?

Family Income and Achievement Test ScoresThe results revealed a strong relationship between family income and test scores, such that the higher the family income, the higher the test score of the child. In this example, family income is the predictor variable, and test score is the outcome variable.

## What makes a good outcome measure?

The extent to which the scores/results are consistent with those produced by a known outcome measure with good validity. For example a new test of muscle function produces scores that are consistent with those achieved in an existing test.## What is outcome measure data?

An outcome measure, endpoint, effect measure or measure of effect is a measure within medical practice or research, (primarily clinical trials) which is used to assess the effect, both positive and negative, of an intervention or treatment. Measures can often be quantified using effect sizes.## What types of variables are there?

These types are briefly outlined in this section.
