What else can I help you with?
When a researcher cannot tell which variable might be causing an observed effect in an experiment the variables are?
confounded
What is the difference between correlation and experiment?
An experiment is when the researcher manipulates the independent variable and records its effect on the dependent variable whilst maintaining strict control over any extraneous variables. A correlation is a statistical relationship between two or more variables. The researcher makes a change in one of the variables to see what is affected.
What is dependant variable?
A dependant variable is a term used in science to identify the response that is measured in an experiment. When a researcher conducts an experiment, he is interested in the outcome, defined as the dependent variable.
What is Hypothesis of a researcher?
The researcher's working theory of what s/he expects the research either to prove or disprove.
What is the entire group that the researcher is studying?
The entire group that the researcher is interested in is called the population or the target population.
A researcher tries to explain or bring about resulting changes in the response variable by performing an experiment which introduces an explanatory variable?
Answer is True... Via ApexVs
Does an observational study or a designed experiment allow the researcher to claim causation between and explanatory variable and a response variable?
designed experiment
When the experiment is complete what does the researcher do?
Repeats the experiment for validity
What part of an experiment does the researcher manipulate?
The researcher manipulates the independent variable in an experiment. This is the variable that is intentionally changed to observe its effect on the dependent variable.
What is the name of the person who conducts experiment?
A person who conducts an experiment is typically called a "researcher" or an "experimenter."
What difference between an observational study and an experiment?
in an experiment, the researcher manipulates a variable
What variable did the researcher change during this experiment?
The researcher changed the independent variable.
Which variable does the researcher intentionally change in a scientific experiment?
The variable that the researcher intentionally changes in a scientific experiment is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable.
What is the primary difference between an experiment and observational study?
In an experiment, the researcher manipulates a variable.
What introduces victor to the study of electricity and galvanism?
a violent thunderstorm, and subsequent conversation with a famous researcher.
What is the difference between factor and treatment in a experiment?
treatment is a factor in which a researcher will apply to an experimental unit and collect the data from the same. factor is a material used by researcher in an experiment in the field .
What should the classical experiment provide the researcher with?
A classical experiment should provide the researcher with reliable and valid data to test a hypothesis. It should allow the researcher to establish cause-and-effect relationships and draw meaningful conclusions based on the results.
