Science Behind It
normal distribution
Normal distribution is very important in fields such as mathematics, physics, and engineering. If the random variable X follows a Gaussian distribution with a mathematical expectation of μ and variance of σ ^ 2, it is denoted as N (μ, σ ^ 2).
source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: Due to its bell shaped curve, with low ends and high middle, symmetrical left and right, and a total area of 1 between the curve and the horizontal axis, it is often referred to as a bell shaped curve.
Exhibition items description:
The exhibition items are a tiltable funnel-shaped device with multiple small balls and small nail posts. Participants tilt the device and watch the balls fall to the bottom after colliding on regular nail posts. When the number of balls falls reaches a sufficient amount, a camel shaped curve will form, showing a normal distribution.
How to Take Part
Participants flip the device and observe the distribution pattern of the ball after it falls; Understand the situation of normal distribution; End the experience and leave the exhibits.
