WEEK 8--8am---9PM EST

Criteria

Feedback

1. Ask A Question

· Is the question clearly stated?

· Is the population clear?

· Are the variables clearly defined?

· Yes

· Yes, but it could be stated a little more clearly.

· Yes, but I think gender is another variable

2. Collect Data

· Do you understand how this data was gathered?

· Does the author state the potential biases?

· Are there any potential problems with how this data was gathered (that have not been addressed by the researcher)?

· Yes

· Yes

· It is minor, but selecting your samples in that way leads to some possible bias, especially if you have siblings with the same last name at A, or something. Also, what is with that first entry for both boys and girls being so high? Weird.

3. Analyze the data

· Are the analyses appropriate for the data? Support/Explain.

· Are the analyses labeled and explained? Support/Explain.

· Are any of the representations of the data misleading or potentially misleading? Support/Explain.

· Do you have any questions?

· No. Some sort of test for significance needs to be used. Maybe the hypothesis testing from module 5 would work?

· Yes, although I have no idea what a strata is!

· No

· No

4. Interpret the data

· Has the question been answered?

· Is this interpretation clearly supported by the analysis? Explain.

· Do you have any questions?

· Yes, but wrong I think. Doing a significance test on this might give you some interesting results… I think your hypothesis might have actually been correct (wasn’t the important number the difference between the means?)

· No

· No

5. Reflection

· Has the author reflected on both positive and negative experiences?

· Has he/she commented on surprising or unexpected results/experiences?

· Has he/she considered how to improve the study?

· No

· No

· No

-The question was stated clearly.

-       The population was not quite clear: is the population all the students in your state or from your local and middle school?

-       Your variables are clear

2. Collect Data

· Does the author state the potential biases?

I understand how the data was gathered.

You did indicate the potential biases: sample and measurement bias

3. Analyze the data

· Are the analyses appropriate for the data? Support/Explain.

· Are the analyses labeled and explained? Support/Explain.

· Are any of the representations of the data misleading or potentially misleading? Support/Explain.

· Do you have any questions?

I was just wondering why you use only one statistics : mean to draw your conclusion.

Could you have also used standard deviation as well?

Why did you use only one graph to represent your information, could have used another representation to further provide other patterns or findings?

4. Interpret the data

· Has the question been answered?

· Is this interpretation clearly supported by the analysis? Explain.

· Do you have any questions?

yes Do you think using just the mean is sufficient to draw your conclusions?

5. Reflection

· Has the author reflected on both positive and negative experiences?

· Has he/she commented on surprising or unexpected results/experiences?

· Has he/she considered how to improve the study?

YES

YES

Need some elaboration on how to improve the study.
