What is a variable in relation to an investigation?
time or length could be two different variables depending in what the investigation was based on
The scientific investigaion of the relationship between two or more variables describes what?
The scientific investigation of the relationship between two or more variables is described as a correlational study or analysis. This approach aims to identify and measure the strength and direction of associations between variables, without manipulating them. Such studies can reveal patterns and potential causal relationships, but they do not establish causation. Understanding these relationships is essential for developing hypotheses and guiding further experimental research.
Is it easier to control dependent variables than independent variables in a scientific experiment?
It is easier to control independent variables
What is a testable variable?
A testable variable is what you test several times for a scientific investigation or medical investigation.
What dependent independent and control variables are in an investigation?
The answer depends on the nature of the investigation.The answer depends on the nature of the investigation.The answer depends on the nature of the investigation.The answer depends on the nature of the investigation.
How many variables does a scientific investigation have?
As many as are necessary, as few as possible.

What type of scientific investigation involves identifying and controlling variables?
laboratory experiment
What is the function of a control in a scientific investigation?
You establish a controlled variable from which you can compare your results from your experimental variables.
What is descriptive investigation?
a descriptive investigation is a scientific ivestigation that collects data which measure or decribe objects or events. it collects qualitative & quantitative data. it includes a question, but no hypothesis ; no variables are manipulated .
What should be done when designing a controlled experiment scientific investigation?
1.) List the needed materials. 2.) Plan the variables. 3.) List the procedures.
What are the three variables that play an important role in a Practical Investigation?
Independent Variables, Dependent Variables and Extraneous Variables.
What is the best number of variables for a scientific investigation?
In an experiment containing a number of possible variables only one of these should be altered in each individual experiment. Otherwise it is not possible to determine which variable is responsible for a particular change.
What are three kinds of variables used in scientific investigation?
In scientific investigations, three key types of variables are independent variables, dependent variables, and controlled variables. The independent variable is the factor that is manipulated or changed by the researcher to observe its effect. The dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Controlled variables are those that are kept constant throughout the experiment to ensure that any observed changes can be attributed solely to the independent variable.
What is something that is part of a scientific investigation that can be controlled or measured?
One example of something that can be controlled in a scientific investigation is the environment in which an experiment takes place. This can include factors like temperature, humidity, or lighting. Measurement variables could include things like time, distance, volume, or weight.
What step of the scientific method involves identifying variables?
The first step of the scientific method requires scientists to observe in order to obtain information. The next step is to formulate a hypothesis.
What is an important step in scientific investigation?
An important step in a scientific investigation is forming a hypothesis.
