Aug 21, Measured in an experiment are the 'signals' sent by a 'system'. Most scientist call this 'Data'. The dependent variable, which is graphed on the y-axis. Explanation: The dependent variable depends on the independent variable. Example: Sarah performed an experiment in which different pressures were exerted on a syringe that contained a gas.
Related questions How can the scientific method be applied to everyday life? Dependent -- is what will be measured; it's what the investigator thinks will be affected during the experiment. For example, the investigator may want to study coffee bean growth. Skip to content Home Social studies What is the factor that is deliberately changed in an experiment?
Social studies. Ben Davis April 18, What is the factor that is deliberately changed in an experiment? Is a factor that changes during an experiment? What are the three variables in a science experiment? Is the part of the experiment not being tested?
What is the factor being tested in an experiment called? Temperature of the water measured in degrees Celsius Amount of sugar that dissolves completely, measured in grams Stirring Type of sugar "More stirring might also increase the amount of sugar that dissolves, and different sugars might dissolve in different amounts, so to ensure a fair test I want to keep these variables the same for each cup of water.
Amount of fertilizer, measured in grams Growth of the plant, measured by its height Growth of the plant, measured by the number of leaves See Measuring Plant Growth for more ways to measure plant growth. Same type of fertilizer Same pot size for each plant Same plant type in each pot Same type and amount of soil in each pot Same amount of water and light Make measurements of growth for each plant at the same time "The many variables above can each change how fast a plant grows, so to ensure a fair test of the fertilizer, each of them must be kept the same for every pot.
Voltage of the electricity, measured in volts Speed of rotation, measured in revolutions per minute RPMs Same motor for every test The motor should be doing the same work for each test turning the same wheel, propeller, or whatever "The work that a motor performs has a big impact on its speed, so to ensure a fair test, I must keep that variable the same. Time measured, in minutes Height of candle, measured in centimeters, at regular intervals of time for example, every 5 minutes Use same type of candle for every test Wind—make sure there is none.
Groups receiving the survey: Teenagers or parents Amount of time that each person listens to music per day, measured in hours Ask the question in exactly the same way to each individual. Teacher location: The teacher is either in the room or not in the room. Fenders: The bicycle either has fenders or it does not "Many engineering projects have alternative designs with independent variables like this one with and without fenders. Riding at the same speed Same size and depth of puddle.
Sample Here is a sample containing the variables and hypothesis. Explore Our Science Videos. The faucet Water pressure, or how much the water is "pushing" "Different water pressure might also cause different amounts of water to flow and different faucets may behave differently, so to ensure a fair test, I want to keep the water pressure and the faucet the same for each faucet opening that I test.
Stirring Type of sugar "More stirring might also increase the amount of sugar that dissolves, and different sugars might dissolve in different amounts, so to ensure a fair test I want to keep these variables the same for each cup of water. Growth of the plant, measured by its height Growth of the plant, measured by the number of leaves See Measuring Plant Growth for more ways to measure plant growth. Same motor for every test The motor should be doing the same work for each test turning the same wheel, propeller, or whatever "The work that a motor performs has a big impact on its speed, so to ensure a fair test, I must keep that variable the same.
Height of candle, measured in centimeters, at regular intervals of time for example, every 5 minutes. Use same type of candle for every test Wind—make sure there is none. Same classroom Same students Same time of day. The rider either gets wet or does not.
