Normal Standard Deviation in Life
The Normal Standard Deviation graph always fascinates me. In the video above you'll see a Galton Board, one where multiple balls always fall in a bell curve. No matter how many times the board is flipped it always lands the same, the events being completely random. When I explored this a little more I found this pattern in even more datasets. To investigate I took a look at the JEE Main test Marks. Here is a graph of the Number of people (population in ranks) VS the Marks. Data Source: JEE Main 2021 Marks vs Rank - Predict your Rank [Rank vs Marks Analysis] (byjus.com) Which on further inspection looks like... you guessed it, a Normal Standard Deviation Curve. Link to dataset to see working: JEE scores 2020 Where the median is, approximately 32. So, the graph does show that the majority of the population scored ... just AVERAGE. These curves, I believe, are trying to tell a story about our general society. You see in these curves, the po...
