Fiction. No real student, family or grade appears.
Measuring classmates and then analyzing the results. Consent, and what happens to the data after.
If you control the variable it is experimental. If you only watch, it is observational and you cannot claim cause.
Sensors on people, multiple trials, units on everything. Our first trials were inconsistent because we were not standardizing rest between them.
Statistics with a purpose. Mean and standard deviation, then a t-test to ask whether two groups actually differ or whether the difference is noise.
ME
It looked convincing in the bar chart and it did not survive the t-test.
Raw data, statistics, and an honest statement that our result was not significant.
