Missy is using a multiple probe across participants design to evaluate the effects of peer tutoring to teach three students to complete division problems. These three students have had no prior instruction in division. Missy MOST LIKELY chose a multiple probe design rather than a multiple baseline design becausE.

Totally agree with Rozella, extraneous variables are a big deal!

Wait, can you really use multiple probe if they have zero scores?

I think option C makes the most sense here.

Not sure if this is the best choice, seems risky with no prior instruction.

A multiple probe design is great for zero baseline scores!

I don't think she's comparing three interventions at once, so D seems unlikely. I lean towards A or C, but I’m not completely confident.

I feel like I saw a similar question about choosing between designs, and it had to do with extraneous variables affecting results. Maybe option C is relevant here?
ET

I think Missy chose this design because the students have no prior instruction, so their baseline scores would be zero. That seems to fit with option A.

I remember that a multiple probe design is often used when you can't have a stable baseline, but I'm not sure if that's the main reason here.

I'm pretty confident that the answer is C. The multiple probe design allows Missy to see if the peer tutoring intervention is effective, even if other factors might cause the students' skills to improve over time.

I think the multiple probe design is used when you want to see if the intervention has an effect, but you don't necessarily need to establish a stable baseline first. That makes sense in this case, since the students have no prior knowledge of division.

Okay, let's see. The key here is that the students have had no prior instruction in division, so their baseline scores will likely be zero. That rules out option A. I'm leaning towards C, since other factors could cause their skills to improve over time.

Hmm, this is a tricky one. I'm not sure if I fully understand the difference between a multiple probe and multiple baseline design. I'll need to think this through carefully.

Option C is a valid concern, but a well-designed multiple probe study should be able to account for that. I think A is the way to go.

That makes sense. It's important to consider the research question when choosing a design.
TA

Option D is interesting, but I don't think that's the right answer here. Missy is looking at the effects of peer tutoring, not comparing multiple interventions.

C) other extraneous variables may cause their skills to improve.

A) the students' baseline scores will be zero.

I see your point, but maybe Missy wanted to see the effects of peer tutoring specifically.
RO

But wouldn't a multiple baseline design be better for comparing interventions?

Haha, imagine if Missy tried a multiple baseline design and the students just kept getting division right from the start. Talk about a boring study!

I agree with Maia. The multiple probe design is better suited when you expect baseline scores to be zero, which is the case here.
MI

That makes sense, it's important to consider that when choosing a research design.

MA
Maia

Option A makes the most sense. If the students have had no prior instruction in division, their baseline scores will likely be zero, making a multiple probe design more appropriate.
JU
Judy

Yes, having baseline scores of zero would make a multiple probe design more suitable for evaluating the effects of peer tutoring.
SA
Salina

I agree, option A seems like the most logical choice in this scenario.
FR

Yeah, I agree. It helps to control for other factors that could influence the results.
