Experimenter expectancy effect refers to the phenomenon where a researcher's expectations influence the results of a study. This bias can manifest in unintentional cues or behaviors that subtly influence participants' responses, thus affecting the outcome of the research. It is essential for researchers to be aware of and take steps to minimize this effect in order to maintain the integrity of their studies.

Which researcher discovered experimenter expectancy effects while conducting the research for his own dissertation?
Robert Rosenthal discovered experimenter expectancy effects while conducting research for his own dissertation in the 1960s. This phenomenon refers to the impact of the researcher's expectations on the participants' behavior and the outcomes of the study, leading to bias in the results.
Is A variable that changes outside the control of the participants an independent variable?
Variables that may affect the results of an experiment are described by the umbrella term "extraneous variable". extraneous variables that actually affect the result without experimenter knowledge is called a confounding variables eg. if the experimenter is testing verbal recall performance, hair color is not going to effect the results. hair color is an extraneous variable, but not compound. but whether or not a subject had a good nights sleep can have a huge effect on the ability to remember words. therefore sleep is a compound variable.
Unintended changes in participants behavior due to cues inadvertently given by the experimenter are called?
Demand characteristics.
Why should an experimenter do after analyzing test results?
After analyzing test results, the experimenter should draw conclusions based on the data, determine whether the results support the hypothesis, and consider the implications of the findings. It is important to communicate the results clearly and accurately in a report or presentation to share the outcomes of the experiment with others.
What kind of study is it when neither the experimenter nor the participants know who is in the control group and who is in the experimental group?
This type of study is known as a double-blind study. It helps to minimize bias by ensuring that neither the experimenter nor the participants can influence the results based on their expectations or knowledge of who is in each group.
What is experimental bias?
Experimenter Bias, also known as Experimenter Expectancy, is made up of all the things an experimenter might unwittingly do to influence the results of an experiment to resemble his hypothesis. You could consider this a self-fulfilling prophecy to some extent.
Which variable is intentionally controlled by the experimenter?
The independent variable is intentionally controlled by the experimenter. This variable is manipulated to determine its effect on the dependent variable.
Which researcher discovered experimenter expectancy effects while conducting the research for his own dissertation?
Robert Rosenthal discovered experimenter expectancy effects while conducting research for his own dissertation in the 1960s. This phenomenon refers to the impact of the researcher's expectations on the participants' behavior and the outcomes of the study, leading to bias in the results.
What is a factor that the experimenter controls or changes?
An independent variable is a factor that the experimenter controls or changes in an experiment. It is manipulated to observe its effect on the dependent variable.
What is the variable adjusted by the experimenter?
The variable adjusted by the experimenter is called the independent variable. This is the variable that is purposely manipulated or changed in an experiment to observe its effect on the dependent variable. The independent variable is under the control of the experimenter.
Which of the following terms describes a variable that is controlled by the experimenter?
The term that describes a variable controlled by the experimenter is the "independent variable." This variable is manipulated to observe its effect on another variable, known as the dependent variable, which is measured in the experiment. By controlling the independent variable, the experimenter can establish cause-and-effect relationships in their research.
Does dyslexia affect a persons life expectancy?
No it has no effect on life expectancy.
What is the variable that is changed by the experimenter in a experiment?
The variable that is changed by the experimenter in an experiment is called the independent variable. This variable is manipulated or controlled by the experimenter in order to observe its effect on another variable, known as the dependent variable.
What does the experimenter deliberately changes while observing?
The experimenter deliberately changes the independent variable, which is the factor that is manipulated or controlled in an experiment to observe its effect on the dependent variable. This allows the experimenter to determine the causal relationship between the independent and dependent variables.
What research methods allows the experimenter to draw conclusions about cause and effect?
Experiments -@TheLilDallas
Is the independent variable the cause or the effect?
Cause. The IV is what the experimenter changes, the DV is the result.
Which variable does a experimenter want to prevent variation?
The variable that the experimenter wants to prevent variation in is the independent variable. This is the variable that is intentionally changed or manipulated by the experimenter to see its effect on the dependent variable. By controlling the independent variable and keeping it constant, the experimenter can ensure that any changes in the dependent variable are a result of the manipulation of the independent variable.
