  • Your null hypothesis is the thing you’re trying to disprove. For example, if I wanted to run a study to asses the effect of adding a certain growth hormone to a cell culture, my null hypothesis would be “there is no effect”. In your case, it would be “there is no difference in how much different things are liked”. From there, you’d run your study, and do your statistical analysis, for which there are different methods based on the type of data, number of groups your comparing, sample size, etc., and I’m not a statistician so I can’t say which methods are best for what you’re planning.

    When it comes to p-value, to really simplify it, you can think of your p-value as the likelihood your null hypothesis is true. That’s not exactly what it means, but it’s an easy way to remember it.



  • A poor analogy, as it’s the same as saying that I should expect a cow to grow mold because a steak will get moldly over time. That said, the conditions that allow many mushroom-bearing fungi to flourish are also ideal for mold growth, so it’s not impossible to see mold on mushrooms. I’ve had to throw out my fair share of monotubs due to the growth of green mold


  • I think it depends. I have three snakes, and I feel that combined they’re less work than a single cat or dog. They’re all in bioactive enclosures with an automatic misting system, so other than changing out the water, care just involves feeding them once a week to once every other week, reading the temps and humidity whenever I walk into the room, and occasionally handling the to inspect for potential issues
