In which experimental research design does each subject received only one treatment combination?
This type of experimental design is sometimes called independent measures design because each participant is assigned to only one treatment group. For example, you might be testing a new depression medication: one group receives the actual medication and the other receives a placebo.
Which term refers to an experimental design element that unintentionally provides subjects with hints about the research hypothesis?
constancy of conditions. Which term refers to an experimental design element that unintentionally provides subjects with hints about the research hypothesis? demand characteristic.
Which term means that subjects in all experimental groups are exposed?
", control group" -Any group which the index group is compared to- constancy of conditions. Ensuring that the time and environment is the same for all the participants. "Means that subjects in all experimental groups are exposed to identical conditions except for the differing experimental treatments." control group.
Which term refers to an alternative explanation beyond the experimental variables?
Confound. An experimental confound means that there is an alternative explanation beyond the experimental variables for any observed differences in the dependent variable.
Which term refers to a treatment combination within an experiment?
Often, the term linkage is used to refer to a treatment combination within an experiment. F. Experiments in which an individual subject is exposed to more than one level of an experimental treatment are referred to as repeated measures designs.
What is the term for a group of subjects that receives the independent variable during an experiment?
An experimental group is a test sample or the group that receives an experimental procedure. This group is exposed to changes in the independent variable being tested. The values of the independent variable and the impact on the dependent variable are recorded.
What is control group and experimental group?
The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment).
What is an experimental group in an experiment?
In a psychology experiment, the experimental group (or experimental condition) refers to the group of participants who are exposed to the independent variable. These participants receive or are exposed to the treatment variable.
What are treatment conditions in an experiment?
In experimental design, a level of an independent variable or combination of levels of two or more independent variables. For example, in an experiment examining the effects of four different drugs on dreaming, research participants or subjects would receive a different drug in each treatment condition.
Which of the following terms refers to the variables that change as the independent variable is manipulated by the researcher?
Therefore, in experiments, a researcher manipulates an independent variable to determine if it causes a change in the dependent variable. As we learned earlier in a descriptive study, variables are not manipulated. They are observed as they naturally occur and then associations between variables are studied.
What is the independent variable in an experiment?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
Which of the following is a term for a variable that researchers do not control and that can affect the results of a study?
An extraneous variable is any variable that you're not investigating that can potentially affect the dependent variable of your research study. A confounding variable is a type of extraneous variable that not only affects the dependent variable, but is also related to the independent variable.
Which of the following refers to the dependent variable in an experimental research design?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured.
What is known to be the experimenter's predicted outcome of a research project?
experiment. Theory. The experimenter's predicted outcome of a research project is thea. research hypothesis.
What does a Nomothetic explanation seek to explain?
Nomothetic explanations seek to identify. One causal factor (or a few factors) that affect a general class of events, outcomes, or conditions.
What is the difference between a correlational study and an experimental study?
In an experimental design, you manipulate an independent variable and measure its effect on a dependent variable. Other variables are controlled so they can't impact the results. In a correlational design, you measure variables without manipulating any of them.
