Pill bug lab chi square
The results show how at the beginning of this experiment the Pill bugs were more attracted to the darker environment but as the time progressed they showed little preference for either side. According to the Chi Test there is a less than 5% chance that the expected results will occur by chance therefore we will reject our null hypothesis.The most common little black bug in the house is the carpet beetle. However, those bugs you see could possibly be grain insects, such as weevils, fleas, pill bugs, or centipedes. See if they fly, leave a trace, or leave a foul smell when squashed. Also, check their shape and distinct physical characteristics, such as hard shells.
