I would like to mathematically demonstrate how important it is to stay home in times like these. My article will be a very short version of the cite below. Let’s start with a simple task:

Begin by asking how a rumor might spread among a population. Suppose on Day 1 a single person tells someone else a rumor, and suppose that on every subsequent day, each person who knows the rumor tells exactly one other person the rumor. Have students ponder, discuss and answer questions like: “How many days until 50 people have heard the rumor? 100 people? The whole school? The whole country?Exponential Outbreaks: The Mathematics of Epidemics

According to Wikipedia, the wisdom of the crowd is the collective opinion of a group of individuals rather than that of a single expert. An explanation for this phenomenon is that there is idiosyncratic noise associated with each individual judgment, and taking the average over a large number of responses will go some way toward canceling the effect of this noise.

We’ll take the results of a YouTube video as an example, to test the wisdom of the crowd. I used Majk’s Show as a dataset. It’s a young local guy that interviews random people on the streets, asking them random questions.

We will agree that any hits above 50% will validate the wisdom of the crowd. Follows a table with results:

We can further categorize the questions and see where the wisdom of the crowd fails specifically. For example, English seems to be below 40% while everything else is above 40%.

In any case, I think I might have set a bit high grading point for the citizens of my country 🙂 But at least they seem to know how to compare two numbers!
