An operational definition specifies how a variable will be measured or quantified in a study. For example, if the variable is "stress," an operational definition might involve measuring stress levels through a standardized questionnaire, such as the Perceived Stress Scale, or by assessing physiological indicators like heart rate or cortisol levels. This allows researchers to consistently assess the variable across different contexts and participants, ensuring clarity and reliability in their findings.
What else can I help you with?
What kind of statistical measure is age?
Technically it is a continuous variable but sometimes (particularly with people) it is treated as discrete because people think of their age in whole years.
What is a variable that can be controlled?
It is called an independent variable. For example, you give some people dark chocolate and other no chocolate at all. You measure their well being. The amount of chocolate is something YOU control, so it is the independent variable. The well being depends on the chocolate. We would expect more dark chocolate would make much happier people. That would be the dependent variable.
What is the definition of 'percentile'?
== == I have seen a good answer in this answer http://wiki.answers.com/Q/What_does_the_98_Percentile_meanPercentile is group of 100 people that are divided by the value of particular variable. This is in the 10th percentile of the group weight.
Is the number of people a discrete variable?
Yes, is a discrete variable.
What are some kinds of independent variables?
The answer depends on the context. A variable can be independent in some studies but dependent in others. Time can be an independent variable in distance-time or speed-time studies but the time (to failure of a component) is a dependent variable. Perhaps confusingly, the same two variables can swap places depending upon the context. Suppose I believe that healthier people are taller (their growth is less likely to be stunted by illnesses) then my independent variable is some measure of their health and the dependent variable is their height. If instead, I believe that taller people are healthier (their parents must have had good genes) then the independent variable is height and the dependent is health.
What is the operational definition for the rate of transportation?
The operational definition for the rate of transportation refers to the quantifiable measure of the movement of goods or people over a specific period and distance. It can be calculated as the volume or weight of items transported divided by the time taken for the transportation process, often expressed in units such as tons per hour or passengers per mile. This definition allows for consistent measurement and comparison across different transportation modes and routes.
What is the definition of idependent variable?
An independent variable is a part of an experiment that might change due to the outcome not being a desired result. The person conducting an experiment about how a medicine might affect a person, might change the number of people tested to gain more insight into the results. The independent variable in that situation would be the number of test subjects.
What does vary inversely mean?
Varying inversely means that as one variable increases, the other variable decreases proportionally, and vice versa. In mathematical terms, when one variable is multiplied by a constant, the other variable is divided by that constant.

If a man tries out a super juice on a group of 50 workers for an hour while they work and another 50 people aren't given anything what is the independent variable?
The independent variable is whatever you change. In your example this would be the super juice. You would measure the amount of work completed; this would be your dependent variable.

Yes, is a discrete variable.

What is difference between a curtrual and a variable?
A cultural refers to the beliefs, values, practices, and norms shared by a group of people, shaping their behaviors and worldview. In contrast, a variable is a measurable characteristic or property that can change and take on different values, often used in research and statistics to analyze relationships and patterns. Essentially, culture is a social construct, while a variable is a quantitative or qualitative measure.
What is the definition of term?
