/sci/ - Science & Math

Hello /sci/ I am a test engineering intern, who has no experience in test engineering or advanced statistics.

My internship consists of riding around a battery operated vehicle until it runs out of batteries and recording some information about each run.

It seems to me the product I am testing is getting worse with each run, but I have only done 20 tests, each lasting about an hour and a half.

I am doing it alone so data collection is slow, but what do you think of these results, see my attached image.

Thanks!
