Hey John, fancy seeing you here. How have you been and how has home schooling turning out for you?
Hey Mike! Everything is going well, and home schooling has been tough lately. Especially math since you basically have to teach yourself some things you do not even know. I am learning population, parameter, sample and statistic
That sounds harsh! Lets go to the park, I could help
Makes a lot more sense now! But what about sample and statistic, what do they have to do with the problems that they give me such as if you wanted to see if self checkout is faster than regular checkout?
That is a good question. Many people forget about that, but it is a very important part of an experiment or an observational study.
So basically, parameter is the topic that is investigated. So if I wanted to conduct an observational study of if self checkout is faster than regular checkout, the parameter is "if self checkout is faster than regular checkout"
It all makes sense now, thanks. I see how every one of those topics relate with each other so you can solve your full observational study data.
So statistics is one of the most important part because it tells you all the numbers you need to know and the main ones as well. A parameter is a descriptive measure for a population while a statistic is a descriptive measure for a sample.
Thanks, once again for helping me! I understand a little bit better now but why don't we go eat something and maybe I will understand a little bit better with a full stomach.
First population is usually the individuals that are being studied in the experiment or observational study. It is usually the total amount of people in the problem or things.
That sounds like a great idea, maybe explaining parameter, sample and statistics will help
Sounds good! I hear all of those topics correlate with each other so the whole problem and solution makes sense.
OH wow, that definitely helps but there is still something missing, and I think it is the statistic, but why does that matter if we already basically solved the problem? Do we really need those numbers?
Glad you brought that out, it is very important and I will tell you why, but first lets walk back to your house as it is getting late.
Sample is an important part of an observation as it is a part of the population where the information was actually collected. This helps bring out the conclusion and the solution in the problems.
No problem man! Take care!
Thanks once again for all your help, I have a test soon on this subject and it really helps, hope to see you soon!
