Which is an example of counterbalancing?
It is counterbalancing , which means testing different participants in different orders. For example, some participants would be tested in the attractive defendant condition followed by the unattractive defendant condition, and others would be tested in the unattractive condition followed by the attractive condition.
What is an example of an independent measures design?
An independent measures design is a research method in which multiple experimental groups are used and participants are only in one group. Each participant is only in one condition of the independent variable during the experiment. An example would be a drug trial for a new pharmaceutical.
What is a counterbalanced experiment?
Counterbalancing is a procedure that allows a researcher to control the effects of nuisance variables in designs where the same participants are repeatedly subjected to conditions, treatments, or stimuli (e.g., within-subjects or repeated-measures designs).
What is an independent measures experiment?
Independent Measures: Independent measures design, also known as between-groups, is an experimental design where different participants are used in each condition of the independent variable. This means that each condition of the experiment includes a different group of participants.
What is counterbalance and example?
Counterbalancing removes confounding variables from an experiment by giving slightly different treatments to different participant groups. For example, you might want to test whether people react positively or negatively to a series of images.
How is counterbalancing calculated?
Using the equation, Fe × de = Fl × dl, the torque for the weight, or effort force, is then 2,000 pounds times 50 feet, or 100,000 pound-feet for the weight. The counterbalance weight, or load force, is then, 100,000 pound-feet divided by 20 feet, or 5,000 pounds.
What is the defining characteristic of an independent-measures research study?
What is the defining characteristic of an independent-measures research study? An independent-measures study uses a separate group of participants to represent each of the populations or treatment conditions being compared.
How do you counterbalance?
Counterbalance in a Sentence 🔉
- A pulley system was used by the movers to counterbalance the weight of the furniture during delivery.
- To counterbalance the threat, the country’s president issued its own grave warning to its enemy.
What does counterbalance mean?
1 : a weight that balances another. 2 : a force or influence that offsets or checks an opposing force. counterbalance.
What are the three types of order effects?
Three basic types of question order effect have been identified: (a) unconditional, in which the answer to a subsequent question is affected by the individual having responded to the prior question but not by the response given on that prior question; (b) conditional, in which the answer to a subsequent question …
What is the correct null hypothesis for an independent measures t-test?
The null hypothesis for an independent samples t-test is that two populations have equal means on some metric variable. For example, do men spend the same amount of money on clothing as women? We can’t reasonably ask the entire population of men and women how much they spend.
When to use counterbalancing in an experiment?
The counterbalancing technique is also used when there are more than two conditions. To consider how the all possible orders of the conditions may affect the results of the experiments, a complete within-subjects design is used again.
How is the sample divided in half in counterbalancing?
With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order. E.g., the first 10 participants would complete condition A followed by condition B, and the remaining 10 participants would complete condition B…
How is counterbalancing used in repeated measures design?
Share: Counterbalancing is a technique used to deal with order effects when using a repeated measures design. With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order.
Which is the correct order to do counterbalancing?
E.g., the first 10 participants would complete condition A followed by condition B, and the remaining 10 participants would complete condition B and then A. Any order effects should be balanced out by this technique. Printed workbooks designed to support students throughout their course.
