What else can I help you with?
What is an activity in which results are observed?
Experiment
What is the factor being tested in an experiment called?
The factor that is being tested in an experiment is called a variable. The factor that is measured or observed is called the dependent variable.
When a researcher cannot tell which variable might be causing an observed effect in an experiment the variables are?
confounded
What type of data do you collect during an experiment?
Experimental data. Information about what conditions are present when measured or observed.
What is the difference between dependent and independent variables?
The independent variable is the variable being manipulated in the experiment in order to show the effect on the dependent variable. It is also called the experimental variable.The dependent variable is the variable being observed in the experiment. Changes in the dependent variable as a result of changes in the independent variable are observed, which is the purpose of the experiment. Dependent variable is also called the response variable.

In an experiment a snail was observed to have moved a distance of 0.5 meters in 2 hours. What rate of movement was observed in this experiment?
In one hour the snail moved 0.25, therefore the speed was 0.25 per hour
In an experiment a snail was observed to have moved a distance of 0.5 meters in to hours what rate of movement was observed in this experiment?
0.5 m in 2 hours would be 1 m per hour.
