Me: Hey, Lil. How was school?
10yo: Productive. Catherine and I spent some time conducting Scientific Research.
Me: What kind?
10yo: We timed how long it would take to spin in circles, get dizzy, and fall down.
Me: That sounds like two physiological events: first, the onset of dizziness and second the point at which the dizziness resulted in catastrophic loss of balance. How did you separate the two?
10yo: We didn't. It's tricky to tell the start of dizziness, but when you fall, you fall.
Me: So what you're saying is that you favored the objective event over the subjective reporting of one?
10yo: Exactly. I spun for six minutes before I fell down. My head hurt at the end.
Me: That was probably a predictable outcome.
10yo: But worth it. Because Michael only made it five minutes before he fell down.
10yo: Unfortunately, Catherine's dad showed up to take her home before she got to spin.
Me: Well, that's just going to skew your whole dataset.
10yo: I know! It was a very disappointing end of the study.
