What is the dependent variable biology?
The dependent variable, as the name implies, is the variable that depends and therefore affected by certain variables, in particular, by the independent variable(s). In comparison, the independent variable is the variable that determines the value of the variable dependent on it.
What is a Dependant variable in biology?
A dependent variable is the variable being tested in a scientific experiment. The dependent variable is “dependent” on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
What is a independent and dependent variable in biology?
Independent vs Dependent Variables
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
What does dependent variable example?
It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
What is the dependent variable answer?
A dependent variable is the variable that changes as a result of the independent variable manipulation. It’s the outcome you’re interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)
What is a dependent variable chemistry?
The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
How do you find the dependent variable in biology?
https://youtu.be/nqj0rJEf3Ew
It's always the dependent variable. And on the x axis the horizontal axis. The independent variable is always placed on the bottom there because you control it.
What is an independent variable in biology example?
An independent variable is sometimes referred to as a predictor variable. That is because this variable helps to “predict” and explain changes in response. For example, the amount of fertilizers, an independent variable, can help predict the extent of plant growth (a dependent variable).
What is a dependent variable in photosynthesis?
Dependant variable: the number of oxygen bubbles given off (the rate of photosynthesis). Controlled variables: the size of the pondweed, the volume of water used and its temperature.
How do you identify independent and dependent variables?
The easiest way to identify which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV) is by putting both the variables in the sentence below in a way that makes sense. “The IV causes a change in the DV. It is not possible that DV could cause any change in IV.”
What is a dependent variable psychology?
The dependent variable is the variable that is measured by the experimenter. In the previous example, the scores on the test performance measure would be the dependent variable.
Is density a dependent variable?
In this sense, some common independent variables are time, space, density, mass, fluid flow rate, and previous values of some observed value of interest (e.g. human population size) to predict future values (the dependent variable).
Is time a dependent variable?
Time is usually viewed as the independent variable for the simple reason that it doesn’t depend on anything else. Time simply ticks by at the same rate wherever you are (in non-relativistic context), independent of other variables so it doesn’t make sense to express time as a dependent variable.
Is weight dependent or independent?
Calorie intake is your independent variable and weight is your dependent variable. You can choose the calories given to participants, and you see how that independent variable affects the weights. You may decide to include a control variable of age in your study to see if it affects the outcome.
Is money independent or dependent?
Think of the independent variable as the “cause” and the dependent variable as the “effect.” The money earned changes depending on the hours worked, so the money earned is the dependent variable.
Is temperature a dependent variable?
An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate.
Is water dependent or independent variable?
In this case, the amount of water is the independent variable because that is what you’re changing in the experiment: one seed gets a lot of water and the other seed only gets a little water.
Is sunlight independent or dependent?
In this case, the number of hours of sunlight is the independent variable and the height of the plant is the dependent variable, because the change in the height depends on the hours of sunlight, not the other way around.
Is Salt a dependent variable?
Independent variables include type of salt (i.e. rock salt, table salt) and amount of salt (i.e. no salt, 1/2 tsp., 1 tsp., 1 tbls.). Time (in seconds) for ice to melt was used as the dependent variable.
Is sugar a dependent variable?
Sugar consumption might be a dependent variable in a study in which you compare a group of children who received specific nutritional classes to a control group of children who did not receive such classes, and you subsequently measure the amount of sugar consumed.
What is the dependent variable in the floating egg experiment?
The dependent variable (also known as responding variable) is the status of the egg in water (sink, submerge, float). The control variable is water temperature.
What type of variable is fertilizer?
In fertilizer rate experiments, the rate of fertilizer is referred to as a continuous variable because there are many possible rates in addition to the ones the researcher selected to use in the experiment.
What type of variable is the water?
dependent variable
The water is the dependent variable. If there is a cause and effect relationship between water and temperature, then the water will change with the temperature change.
Is soil a controlled variable?
Controlled variable(s): quantity of water, type of soil, depth of seeds, source of light, concentration/type of fertilizer (if any); temperature of the room, etc.
