Complete question:
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?
Answer:
Here,
Independent variable (IV) is: the color of the light produced by the lamp (red, orange, yellow, green, or blue)
We are also told only 10 participants are available.
All 10 participants are being exposed to all five levels of the color variable in the same order.
Counterbalancing is said to be a technique used when establishing task order. It helps prevent introduction if cofounding variables.
Dr. Lyte will need to use counterbalancing technique in this scenario because some of the participants may be unable to understand difference in similar colours. Example some participants may not be able to differentiate between orange and red when the red colour comes after orange.
But using counterbalancing technique, Dr. Lyte can avoid such an error.
Answer:
6/15 divided by 6
Step-by-step explanation:
Answer: B
Step-by-step explanation:
The only labeled angle is 111
We can conclude that angle 3 is also 111
1 and 2 are both less than 90
Therefore, 1 is 69, 2 is 69, and 3 is 111
If something is to the power of 1/2, it is the same as the square root of that number. So, what's the square root of 49?

Maximum: 30
Median: 26

The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.</span>
