- A bell curve is a graph depicting the normal distribution, which has a shape reminiscent of a bell. The top of the curve shows the mean, mode, and median of the data collected. Its standard deviation depicts the bell curve's relative width around the mean.

Feb 9, 2021 · This tutorial shares 6 examples of real-world phenomena that actually follow the normal distribution. Example 1: Birthweight of Babies It’s well-documented that the birthweight of newborn babies is normally distributed with a mean of about 7.5 pounds.
- Height. The height of people is an example of normal distribution. Most of the people in a specific population are of average height. The number of people taller and shorter than the average height people is almost equal, and a very small number of people are either extremely tall or extremely short.
- Rolling A Dice. A fair rolling of dice is also a good example of normal distribution. In an experiment, it has been found that when a dice is rolled 100 times, chances to get ‘1’ are 15-18% and if we roll the dice 1000 times, the chances to get ‘1’ is, again, the same, which averages to 16.7% (1/6).
- Tossing A Coin. Flipping a coin is one of the oldest methods for settling disputes. We all have flipped a coin before a match or game. The perceived fairness in flipping a coin lies in the fact that it has equal chances to come up with either result.
- IQ. In this scenario of increasing competition, most parents, as well as children, want to analyze the Intelligent Quotient level. Well, the IQ of a particular population is a normal distribution curve; where the IQ of a majority of the people in the population lies in the normal range whereas the IQ of the rest of the population lives in the deviated range.
Oct 23, 2020 · When plotted on a graph, the data follows a bell shape, with most values clustering around a central region and tapering off as they go further away from the center. Normal distributions are also called Gaussian distributions or bell curves because of their shape.
Oct 3, 2018 · To draw a normal curve, we need to know the mean and the standard deviation. Example 1: Suppose the height of males at a certain school is normally distributed with mean of μ =70 inches and a standard deviation of σ = 2 inches.
Oct 11, 2023 · A bell-shaped curve, also known as a normal distribution or Gaussian distribution, is a symmetrical probability distribution in statistics. It represents a graph where the data clusters around the mean, with the highest frequency in the center, and decreases gradually towards the tails.
LEARNING OBJECTIVES. Describe properties of the normal distribution. Apply the Empirical Rule for normal distributions. The normal distribution is the most important of all the distributions. It is widely used and even more widely abused. Its graph is a symmetric, bell-shaped curve.
Aug 12, 2022 · We can graph a normal curve for a probability distribution on the TI-83/84 calculator. To do so, first press [Y=]. To create a normal distribution, we will draw an idealized curve using something called a density function.
