![]() The more samples you take, the closer your average will be to the true average. This large number is where the patience comes in. Instead, what is usually practised is that a very large number of samples are drawn from the total population. Keeping the above example in mind, in almost every case the population is so big that the true height cannot be correctly averaged. This average will be a true representation of the population of your interest. Then sum up the 50 heights and divide them by 50 to get an average. Talk to everyone in the room and get their heights. ![]() Sum them up and divide the number by 5 to get an average (which would be 5 ft 5 something inches) and say that it represents the average of the total population in the room orĢ) you can be proactive. If you were to tell me the average height of people in the room, you can do the following two things.ġ) You can be lazy and just use the five heights you already know. What you have here is a sample from a larger population of 50 people in the room. So you know their heights and let us suppose that the heights are 5 feet (ft) 4 inches (in), 5 ft 3 in, 5 ft 9 in, 5 ft 6 in, 5 ft 5 in. I am just going to use their heights for reference here so no need to get creative. You know everything about your best friends. Let us assume that in a room in your university or office, there are 50 people and you are best friends with five of them. To answer that question we will have to look at statistics.īecause the experiment that we are about to conduct is based in statistics (well sort of), I will introduce the concept now with an analogy (or rant). ![]() The first two ingredients are understandable, but you may ask why did I specifically mention patience. and most importantly you will need patience.A Python environment where you can run some code, see previous post to set this up or read till end.Now that we know a little bit about Pi let us perform a computational experiment to determine its value.Ĭomputational Experiment: Ingredients and methodįor this experiment you will need the following ingredients. however the rational number works well in many situations because mostly we round of as being 3.14. is an irrational number, which means that it cannot be written as, as taught in schools. The quantity referred to as can be calculated as the ratio of the circumference of a circle to its diameter. I found out about it from my significant other while writing about this post. But as always before that some background (or ranting).ĭid you know that there is something called the Pi day? I didn’t. To this end, I am going to put together a concise Pythonic example which would help you calculate the value of Pi ( ) ( yes the number approximated by the fraction or rounded off to 3.14 ). Instead it provides exposure on using the Python programming language in a scientific context. This blog doesn’t attempt to teach you Python. As discussed before, there are many resources available on the internet for learning Python. Building on the previous post, which covered a very simple example using a for loop, this post will take things up a notch.
