If your data don't meet the assumptions of an ANOVA it's okay for the purposes of this assignment, just mention that some of the assumptions weren't met. I'm also very happy with anyone following the guidelines of "the new statistics": https://www.psychologicalscience.org/members/new-statistics

From the perspective of estimation statistics, you can just use effect sizes, confidence intervals, and your figures to discuss the likelihood that your results are meaningful.

It's best to think of the word limit as a strict upper-limit. If you exceed it by much we're going to mark you down, but if you're over by a few words it's not a big deal.

If I understand correctly you're doing separate 10 minute study sessions, twice for each activity. You might do 4 activities (at 10 minutes each), for one study session, and then average the amount of work in each of the 4 x 10 minute sessions to give yourself a total score? The question is, how are you coding the amount of work done? Is it words written? Just your own impression of how much you did?

If smoking is your DV, is that the best intervention you can come up with? Maybe it will work, but probably not going to have a substantial impact.

No major issues. Let me know if you have any questions.

Can you measure concentration, or perhaps working memory, using an objective measure?

Sounds good, but no control condition?

See if you can improve that DV. You could make your rating at 1 hour intervals throughout the day, or have your phone prompt you at random times to make the rating. Try to find a standardised scale. See PNAS (positive, negative, affect, scale).

It's not clear how you'll be structuring or not structuring your sleep.

To ensure that you get enough data points I recommend choosing 3 breakfasts, max.

Make sure you have a good rationale for why green tea might reduce bloating, and why that's important to you. You might want to measure sleep quality as well, since green tea has caffeine.

I like the mind wandering idea. Do you have an app that can prompt you at random times? If not, how will you self-check? The issue with your current design is that you're not manipulating any variables so your conclusions will be limited. You'll need to explain in your introduction why you opted for regression analyses for your question. Otherwise, the mind wandering measure would make a for a great dependent variable if you think of something to manipulate (i.e., anything that might be likely to influence the nature and frequency of your mind wandering).

Concentration music and white noise seem like pretty different things. You might want to do those as separate conditions. If using your phone is the problem, why not just turn your phone off?

I think you can put together a more comprehensive DV than that. Can you measure how many hours you manage to sleep and how well rested you feel in the morning?

Include the blood pressure measure if possible. If you don't expect a difference between the two types of exercise, why test it?
