Lauren has a big social studies test coming up. She knows that she needs to spread out her study sessions over a

period of time. She develops a schedule in which each session is divided up evenly among her available days.

What strategy is Lauren is using?

Intro

pacing

Explanation:

Pacing is a study strategy in which a student may spread out the study material over a given number of study periods and work through the study material at his/her own pace.

This is the study pattern that Lauren is using to prepare for her Social Studies test. This method allows her to work through the material according to her own schedule in preparation for the test.

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.
