The dependent variable is the one you measure. In this case, it would be the electrical resistance, measured in Ohms.
An easy way to remember is to note that the resistance changes based on the material. The resistance is dependent on the material used, and thus the resistance is, in this case, the dependent variable.

What effect does the amount of fertilizer have on the growth of a plant what would be the independent variable?
Increasing the amount of fertilizer can lead to increased plant growth due to the availability of nutrients. The independent variable in this scenario would be the amount of fertilizer applied to the plant.
What is more conductive lead or copper?
Copper is more conductive than lead. Copper has a higher electrical conductivity, making it a common material used in electrical wiring and electrical components. Lead has lower electrical conductivity compared to copper.
How does the concentration of NaCl affect the conductivity of a solution?
The concentration of NaCl in a solution directly affects its conductivity. Higher concentrations of NaCl result in higher conductivity, as more ions are present to carry electric current. Conversely, lower concentrations of NaCl lead to lower conductivity due to fewer ions available to conduct electricity.
How can one test plates for lead content?
To test plates for lead content, one can use a lead testing kit that is specifically designed for detecting lead in dishes. These kits typically include testing swabs or solutions that change color in the presence of lead. Simply follow the instructions provided in the kit to test the plates for lead content.
What insights can be gained from analyzing the relationship between conductivity and concentration in a conductivity vs concentration graph?
Analyzing the relationship between conductivity and concentration in a conductivity vs concentration graph can provide insights into the relationship between the amount of ions in a solution and its ability to conduct electricity. A direct relationship between conductivity and concentration suggests that higher concentrations of ions lead to higher conductivity, indicating a stronger ability to conduct electricity. This relationship can be used to understand the ion concentration in a solution and its impact on its electrical properties.
How do you control the dependent variable?
Technically you can't control the dependent variable. However, by controlling and monitoring the Independent variable, (the variable which determines the dependent variable) you could lead the dependent variable to produce favourable results.
What is a independent variable in mathematical form?
An independent variable is a variable that is manipulated or controlled in an experiment to observe its effect on a dependent variable. In mathematical terms, it is often represented as ( x ) in a function ( y = f(x) ), where changes in ( x ) lead to changes in ( y ). The independent variable is considered the input, while the dependent variable is the output that depends on the input value.
Why do all of the parameters except the independent variable have to be cntrolled?
Controlling all parameters except the independent variable is essential to isolate the effects of the independent variable on the dependent variable. This ensures that any changes observed in the dependent variable can be attributed solely to the manipulation of the independent variable, thereby enhancing the validity and reliability of the experiment. Without controlling these parameters, confounding variables could introduce bias and lead to inaccurate conclusions.
Are lead and pyrite comparable in electrical conductivity?
Generally speaking, no, they are not. Lead is a pretty good electrical conductor, but pyrite (iron disulfide), which has variable electrical conductivity, might actually be tagged as a semiconductor.
In question 7 suppose your hypothesis is that job stress apears to lead to reduced job effiency In that case job stress is the variable?
a. dependent
What are the factors that effects the conductivity of pencil lead?
The factors that affect the conductivity of pencil lead include the quality of the graphite in the lead, the hardness of the pencil lead, and any impurities present in the lead. Higher quality graphite and softer leads typically have higher conductivity, while impurities can decrease conductivity. Additionally, the pressure applied when writing or drawing with the pencil can also impact conductivity.
What are examples of intervening variable?
Intervening variables are factors that mediate the relationship between an independent variable and a dependent variable. Examples include motivation in the relationship between study habits (independent) and academic performance (dependent), where motivation influences how effectively study habits translate into grades. Another example is stress as an intervening variable between work hours (independent) and job satisfaction (dependent), where increased work hours may lead to higher stress, subsequently affecting job satisfaction.
What does dependent mean in math?
An independent variable is basically a variable that can be any number. The dependent variable is the variable calculated from the independent variable. For example, I do contract work where I get paid for every hour of work I do in a given week. If I work more hours, my paycheck is bigger. So in this case the number of hours I work is the independent variable (it can, in theory, be anywhere from 0 to 40 or more hours each week), and the dependent variable is the amount on my paycheck (it is a variable too, but it directly depends on the number of hours I worked).
What effect does the amount of fertilizer have on the growth of a plant what would be the independent variable?
Increasing the amount of fertilizer can lead to increased plant growth due to the availability of nutrients. The independent variable in this scenario would be the amount of fertilizer applied to the plant.
How does the number of speakers affect the amount of noise in a room What is the dependent and the independent variable?
The number of speakers in a room generally increases the overall noise level, as more voices contribute to the sound intensity. As the number of speakers rises, the cumulative sound they produce can lead to higher decibel levels and increased auditory clutter. In this scenario, the independent variable is the number of speakers, while the dependent variable is the amount of noise measured in the room.
What is an example of a real world relationship where there is no clear independent or dependent variable?
A real-world example of a relationship with no clear independent or dependent variable is the interaction between stress and sleep quality. Increased stress can lead to poor sleep, while lack of sleep can also heighten stress levels, creating a bidirectional relationship. In this scenario, both variables influence each other, making it difficult to designate one as independent and the other as dependent.
What is Situation-Relevant Confounding Variable?
A situation-relevant confounding variable is a third variable that is related to both the independent and dependent variables being studied, which can lead to a spurious relationship between them. It is crucial to identify and control for situation-relevant confounding variables in research to ensure that the true relationship between the variables of interest is accurately captured.
