Spokesperson Submits for the Group
To earn credit for this assignment, your group's Spokesperson needs to submit the Lab 1 Group Submission assignment on Webcourses. That submission will be applied to the entire group … so
only
the Spokesperson needs to submit … really, it’s
only
one submission for the whole group.
Have each group member
add themselves to a group
together in Webcourses. This is not how to find a group.
Don’t do this part until you’ve already met as a group
.
Upload
a single file
(pdf, png, or jpg) containing your group's Lab 1 submission by the deadline. Only your most recent submission will be scored.
Have
more than one group member
check your group’s submission against the requirements above. If you find a mistake, no problem. Just upload again. Only your most recent submission will be scored.
All group members will receive the same score unless there is a problem with the effort put forth by you or a member of your group. If that’s the case in your group, send a message in Webcourses to your TA or lab instructor.
Lab 2: Comparing Two Data Sets Coordinate within your group Working in a team isn’t easy. That’s why it’s one of the learning objectives for this course. The easiest way to find group members is in your weekly lab meeting. You’ll need to work with a group (4 students firm max) to earn full credit on this lab. You can stay with the same group or find another group, if you need. Either way, Webcourses will treat Lab 2 groups as separate from Lab 1 groups. That means your group for this lab assignment will need to repeat the process of each member adding themselves to a group (labeled “Lab 2 group ___”) in Webcourses. Once you have your group sorted out, choose new group roles and spend ~10 minutes sharing any new thoughts about the items in the We Are One Fermilab poster and Google re:Work graphic. Holmes’ t’ analysis tutorial You’ll use the Statistics Summary by Cornell Physics prof. Dr. Natasha Holmes as a manual for how to analyze data for this investigation. It requires you to compare two sets of measurements and make a determination of whether you think the two are different or too similar to differentiate. That’s described in sections 1-3 of Holmes’ manual. If you’re familiar with a Student’s t-test, this is similar but you’ll need to use Holmes’ method for full credit on this assignment. Work through this Comparing Means Tutorial with your group to learn how you’ll be expected to perform the data analysis for this investigation. Aim to get at least this far by the end of your first week of this investigation. Submission requirements Your group’s lab report will be scored using the rubric below. Even if your TA, instructor, or another student gives conflicting instructions, the written requirements below are what you'll be graded on unless you have written approval from the Lab instructor. Credit for each rubric section will be awarded at only the points-levels listed, not partially between rubric levels. You’ll use the PPDAC framework to structure investigations in the course: Problem, Plan, Data, Analysis, Conclusion. If you think that’s interesting, you can read more at the GIS wiki or MacKay’s and Oldford’s really interesting paper where they use Michaelson’s 1897 speed of light investigation as an example of how their PPDAC framework works. · Problem (0 points, since it’s given for this investigation): Use mobile app magnetometer (see the PhyPhox How-To) and Holmes t’ to investigate the following question: · For a location outdoors and at least 5 meters away from other electronic devices, vehicles, and buildings, determine whether the Northward component of the Earth’s magnetic field measured at one time is different from the same measurement at a different time at least 2 hours later. Then, comment on how your results compare to the Bz GSM measurements for those same times made by the NOAA Real-Time Solar Wind program. Note: the times shown are in UTC, but lots of time zone converters are on the web. · Plan (4 points max.) · 2 pts: Plan is appropriate for the research question and includes calibration of the data acquisition (see the PhyPhox How-To). · 4 pts: The requirement above is met and doesn’t present data beyond what is needed for answering the research question (e.g., more than two data sets, quantities or components not needed for the analysis) · Data (4 points max.) · 2 pts: Sufficient data are collected to show variation around a constant value and calibration procedure is described (see the PhyPhox How-To). · 4 pts: The requirement above is met and a description is present for if and why any data were omitted (e.g., any extraneous data deleted or cropped extraneous from beginning or end of trial, analysis used only a subset of data collected) · Analysis (14 points max.): This part is worth more points than any other section because it’s important your group can do this type of analysis. You’ll need to use a Python notebook (here’s a template) and perform the Holmes t’ analysis shown in the Comparing Means Tutorial. A single group member should not be solely responsible for these calculations. · 4 pts: two data sets were read into a Python notebook with first few rows of each data set shown · 8 pts: The requirement above is met and the two sets of relevant measurements are shown in a single histogram · 14 pts: The requirements above are met and a t’ calculation is present according to section 3 of Holmes’s Statistics Summary; using another kind of t-test will not be awarded credit · Conclusion (6 points max.) · 2 pts: The choice of research question is clear and an answer to that question is clearly stated. · 4 pts: The requirement above is met and it explicitly describes how the results of the Holmes t’ analysis support the conclusion. · 6 pts: The requirements above are met and describes whether the results seem consistent with the NOAA Bz GSM measurements for those times (no calculations are needed to compare lab measurements to NOAA data). · References (4 points max.): Must include Holmes’ Statistics Summary at minimum: Holmes, N. G. (Aug 2020) Statistics Summary. Physport. physport.org/curricula. Don’t cite office software (Google Docs, Excel, etc), but do cite any software imported in the notebook (e.g., Matplotlib). Purdue OWL is a good resource for APA formatting. · 4 pts: references appear in APA format and include Holmes’ Statistics Summary · Format (4 points max.): Choose one of the format options below for your submission. They are designed to give you practice communicating complex information concisely. You do not need to submit a traditional lab report in addition to this, only one of the four options below. · 4 pts: All evidence for credit awarded by the rubric items above appears in a single uploaded file adhering to one of these format options: · A Python notebook with all code cells run and their output shown, markdown cells used for any explanation required above, and the name and group role listed for each member · 1-2 paragraph email to a non-scientist relative or friend with 1-2 images attached (300 words max) with the name and group role listed for each member · Four social media posts (e.g., 4 screenshots placed in a single file to upload) with the name and group role listed for each member · One-page infographic (e.g., a single slide using PowerPoint, Google Slides, or similar tool) with the name and group role listed for each member · Work Breakdown Structure (4 points max.): See the WBS guidelines for details. The WBS does not need to be embedded into the report format above and may be a 2nd page (but still in one single file upload). This is a good time to make sure everyone has added themselves to the Webcourses group for this assignment. · 0 pts: investigation was performed individually, without group collaboration · 4 pts: WBS is present and lists the responsibilities for each group member Spokesperson Submits for the Group To earn credit for this assignment, your group's Spokesperson needs to submit the Lab 1 Group Submission assignment on Webcourses.
