Question

Textbook- Research Methods and Statistics 5th edition (Jackson) Dr. Lyte wishes to study speed of Reaction Time to press a button in response to the onset of a lamp. The independent variable (V) is the color of the light produced by the lamp (red, orange, yellow, green, or blue) Since only 10 participants are available, she elects to administer the IV within-subjects with all 10 participants being exposed to all five levels of the color variable. The order of the color of the light presentation is to be counterbalanced. Using concepts from the textbook, why would Dr. Lyte need to use counterbalancing in this scenario?

Explanation / Answer

Counterbalancing is a technique used to avoid the introduction of confounding variables. In usability testing, this technique is most commonly used when establishing task order.

(IV) is the color of the light produced by the lamp

If all 10 participants are being exposed to all five levels of the color variable in the same order.

Then maybe it could be a case that most of the participants unable to understand much difference in orange after red.So we could assume that there is some issue with orange.But in fact, it's because of its order.SO if we do counterbalancing in this scenario then we can avoid such error cases
