What are Variables in Science? - Definition, Types & Examples In science, a variable is any item, factor, or condition that can be controlled or changed. There are three types of variables in scientific experiments, but we will define them later in the lesson. First, let's discuss why scientists use experiments.et's use an example that may assist you to understand these two types of variables. You have a plastic container with water inside. You place the container in a metal box and raise the temperature.

Variable (computer science) Variable (computer science) In computer programming, a variable or scalar is a storage location paired with an associated symbolic name (an identifier), which contains some known or unknown quantity of information referred to as a value.

Factor Variables What factor variables are. A factor is a vector whose elements can take on one of a specific set of values. For example, Sex will usually take on only the values M or F, whereas Name will generally have lots of possibilities. The set of values that the elements of a factor can take are called its levels. If you want to add a new level to a factor, you can do that, but you can't just change elements to have new values that aren't already levels. Here's an example.

Variables Anything that can vary can be considered a variable. For instance, age can be considered a variable because age can take different values for different people or for the same person at different times. Similarly, country can be considered a variable because a person's country can be assigned a value. Variables aren't always 'quantitative' or numerical. The variable 'city' consists of text values like 'New York' or 'Sydney'. We can, if it is useful, assign quantitative values instead of (or in place of) the text values, but we don't have to assign numbers in order for something to be a variable.

Reinforced concrete Reinforced concrete (RC) is a composite material in which concrete 's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength and/or ductility.oncrete reinforced with fibers (which are usually steel, glass, or plastic fibers) is less expensive than hand-tied rebar, while still increasing the tensile strength many times. The shape, dimension, and length of the fiber are important.

biology variables Controlled variables, sometimes called constant variables. variables that are kept constant or unchanging. For example, if you are doing an experiment measuring the fizz released from different types of soda, you might control the size of the container so that all brands of soda would be in 12-oz cans.

- Defining Variables. Variables can be defined as any aspect of a theory that can vary or change as part of the interaction within the theory. In other words, variables are anything can effect or change the results of a study. Every study has variables as these are needed in order to understand differences.here is no limit to the number of variables that can be measured, although the more variables, the more complex the study and the more complex the statistical analysis. The most powerful benefit of increasing our variables, however, is control.

Variables in Your Science Fair Project These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To ensure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens.

concrete verb. The definition of concrete is something real. An example of concrete is evidence that the world is not flat. Concrete is defined as a mixture of cement sand, gravel and water which dries hard and strong and is used as a material for building. 1  Typical concrete is made out of two different types of aggregate substances: a course aggregate such as gravel and a fine aggregate such as sand.

Concrete FAQ & Do-It-Yourself Tips Set time – A measurement in hours and minutes of the hardening of concrete to resist a measure of penetration. Slump – A measure of consistency of freshly mixed concrete, measured in inches. It is the distance that freshly mixed concrete subsides when a conical mold (slump cone) is lifted from the test specimen.

Control Variable Definition: A control variable is a variable that is held constant in a research analysis.The use of control variables is generally done to answer four basic kinds of questions: 1.Is an observed relationship between two variables just a statistical accident? 2.efinition: A control variable is a variable that is held constant in a research analysis.

- Variable definition. A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters $x$, $y$, and $z$ are common generic symbols used for variables. Sometimes, we will choose a letter that reminds us of the quantity it represents, such as $t$ for time, $v$ for voltage, or $b$ for bacteria.

For instance, an investigator may want to measure changes in strength. Strength would be the conceptual variable.

- Extraneous variables are defined as any variable other than the independent and dependent variable. Control variables are variables that are kept the same in each trial. Lastly, the moderator variables are variables that increase or decrease the relationship between the independent and dependent variable.

- Definition of Dependent Variable. Dependent Variable is a variable whose value depends on the values of one or more independent variables. 1  In p = 4q, p is the dependent variable, because its value depends on the value of q.  In z = 3x2 - 2y3, z is the dependent variable.
