What variables do you have to control in testing the efficiency of different bikes?
Some variables to control when testing the efficiency of different bikes include rider weight, riding conditions (e.g., terrain, weather), tire pressure, gear ratio, and testing methodology (e.g., standardized course or distance). Controlling these variables ensures a more accurate comparison between the bikes.

What does the word constants mean in a experiment?
In an experiment, constants are variables that are kept consistent and unchanged throughout the testing process. These variables help ensure that any changes observed in the experiment are due to the manipulated variables and not external factors.
Why was the development and use of perry rope and pulley apparatus necessary in the testing of this hypothesis?
The pulley system was necessary for testing the hypothesis because it allowed for the measurement of force and distance required to lift the weight. By using a pulley, scientists could effectively manipulate and control the variables involved in the experiment, making it more accurate and reliable. The system also helped in achieving consistent and repeatable results, essential for testing and validating the hypothesis.
How is the energy efficiency rating of any unit determined?
The energy efficiency rating of a unit is typically determined by measuring its energy consumption against its output, using standardized testing procedures and calculations. This rating is often displayed as an Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER) for cooling systems, or a Coefficient of Performance (COP) for heating systems. A higher rating indicates better energy efficiency.
What are two variables held constant when testing boyles law in manometer?
Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
Why it is important to test materials of the same thickness?
Testing materials of the same thickness is important to ensure consistency and accurate comparison of properties such as strength, durability, and flexibility. It allows for a fair assessment of performance under similar conditions and can help eliminate confounding variables that may impact test results. Additionally, testing materials of different thicknesses may not provide meaningful data for applications where material thickness plays a crucial role in performance.
Why do you need to keep variables the same?
In programming, variables change all the time. In scientific testing you control variables to determine what other changes occur.
Why is it it important to control variables in an expeiement?
It is important because without controling the variables, you will be testing more than one thing in the expirament at a time. you could get different answers. you only want 1 variable in science expiraments. you might also want a control, with the "normal one" to compare the expiraments with the variables to.
Andrea is testing balloon rockets by using balloons with different amount of air Identify the three variables Andrea will need to control?
smoothness,weight and strenght
What are controlling variables?
== ==
What are control and variables?
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
Variables in an experiment whose effect you are testing?
'Known' Variables
Is there another way to study the world other than by doing a controlled experiment?
Scientisists do mant different controlled expirements to see different results. To conduct a fair expirement, you must control all of the variables expect for the one you are testing.
Variables that are always different between the experimental and the control groups are?
Independent variables. If the treatment has no effect , the dependent variables for both the control and experimental group may be the same. cw: In some studies, there is no specific control group. For instance, in a drug study where subjects are given a random amount of the drug (from 0 up to some presumed safe level) then you cannot easily tell what the "experimental" group is -- you can't compare everyone else to the two subjects who got a placebo (0 mg/kg). You can tell whether the treatment is having a linear effect, etc.
What is fair testing in science?
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
How would you explain testing how two types of soap work using control and variable?
The control is what you're washing, amount of dirt, kind of dirt, temperature of water. The kind and amount of soap are variables, although when using the same kind in different amounts, the kind is control. The temperature of water is also control and variable depending on the test.
What is fair test?
A fair test is when you test something equally changing the variables but keeping everything else the same
What are examples of variables?
For example if your testing different types of fertilizers, then some plants may grow tallershort/not at all. I got this from a web site
