Please help me in answering in this case question ASAP:
You are walking in your backyard and see an itsy bitsy spider climbing up a waterspout with ease. It is a hot summer day, so you wonder if the itsy bitsy spider could climb up the waterspout in the rain. You have decided that the waterspout would be too slippery for the spider to climb when it rains. If a
waterspout is drenched with rain then the spider won’t be able to climb it. You decide to build an experiment to test your prediction. You collect several of the same species of itsy bitsy spider and build identical waterspouts in lab. A machine in lab is designed to simulate rain. You have all your spiders climb up the waterspouts without the rain machine on, then with the rain machine on. The experimental results (data collected) supported the null hypothesis.

What is the Dependent Variable in this study? Explain!
How was one confounding variable controlled during this study? Explain! What data would support your hypothesis? Explain!
According to the study could the itsy bitsy spiders crawl up the waterspout in the rain? Explain!
Explanation / Answer
1) This can be classified as a type of a case control study where you wanted to find out whether the spider can climb the waterspout in rainy conditions. Your control was that the spider can climb the waterspout in dry conditions.
2) Initial observation : The bitsy spider can easily climb up the waterspout when its dry.
3) Inductive reasoning is the process where you try to prove something by giving evidence for it. Here by doing the experiment you are inductively showing that the spider cannot climb the waterspout in rains.
4) The independent variable is variable that you have full control over i.e. you can change and fix their value according to your wish. Here the amount water to pour in the rain machine, number of spiders chosen, height of your experimental setup etc are independent variable.
5) Here the dependent variable is the ability of the spider to climb the water sprout. You can control all the other conditions but you cannot control the climbing or not climbing of the spider.
6) The control variable was the rain or no rain i.e. wet or dry waterspout. Your control experiment was to show that the spider can climb the dry waterspout.
7) Your hypothesis is - if a waterspout is drenched with rain then the spider won’t be able to climb it.
When several spiders can climb the waterspout in dry conditions but cannot climb the rain simulated conditions then it will support your hypothesis.
8) The question says that the data collected supported the null hypothesis which was - if a waterspout is drenched with rain then the spider won’t be able to climb it.
Hence we can safely say that the bitsy spider won't be able to climb the waterspout in rain.
