Alab researcher wants to find out whether mice will run through a maze quicker during the day or at night, after training. he has 100 mice available. he randomly assigns 50 of them into ech group. he trains the first group to run the maze ar 9: 00am and trains the sevond group to run the maze ar 9: 00 pm. each mouse is trained the same way, and the last 3 years run times are recored. describe what is being measured in this experiment and what variable is being manipulated?

In this case, since the run times are the one being compared and recorded, therefore the data being measured in the experiment is the run times.

The difference of the two groups of mice is the time of the day that the mice run, day or night. Therefore the variable being manipulated is the time of the day.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
