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.
How can you determine if something contains lead?
To determine if something contains lead, you can use a lead testing kit or have it tested by a professional laboratory. Lead testing kits are available at hardware stores and can detect the presence of lead in various materials such as paint, water, and soil. Professional laboratories can provide more accurate and detailed results. It is important to test for lead, especially in older homes or products, as exposure to lead can be harmful to health.
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.
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?

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 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.
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.
What is the relationship between temperature and air conductivity?
The relationship between temperature and air conductivity is that as temperature increases, air conductivity also increases. This means that higher temperatures can lead to better conductivity of electricity through the air.
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 can I test for lead in soil?
To test for lead in soil, you can use a lead testing kit that is specifically designed for soil testing. These kits typically include instructions on how to collect soil samples and perform the test. Alternatively, you can send a soil sample to a laboratory for professional testing.
What is an example of a confounding variable?
A confounding variable is an extraneous factor that can influence both the independent and dependent variables in a study, potentially skewing the results. For example, in a study examining the relationship between exercise and weight loss, diet could be a confounding variable, as it impacts both the amount of weight lost and the effectiveness of exercise. If not controlled for, diet may lead to incorrect conclusions about the impact of exercise on weight loss.
