This normal distribution calculator (also a bell curve calculator) calculates the area under a bell curve and establishes the probability of a value being higher or lower than any arbitrary value X. You can also use this probability distribution calculator to find the probability that your variable is in any arbitrary range, X to X₂, just by ...

Today, we're interested in normal distributions. They are represented by a bell curve: they have a peak in the middle that tapers towards each edge. A lot of things follow this distribution, like your height, weight, and IQ. This distribution is exciting because it's symmetric – which makes it easy to work with. You can reduce lots of complicated m...
To continue our example, the average American male height is 5 feet 10 inches, with a standard deviation of 4 inches. This means: Now for the fun part: Let's apply what we've just learned. What's the chance of seeing someone with a height between between 5 feet 10 inches and 6 feet 2 inches? (That is, between 70 and 74 inches.) It's 34%! We leverag...
Knowing this rule makes it very easy to calibrate your senses. Since all we need to describe any normal distribution is the mean and standard deviation, this rule holds for everynormal distribution in the world! The challenging part, indeed, is figuring out whether the distribution is normal or not. Want to learn more about calibrating your senses ...
Oct 23, 2020 · The empirical rule, or the 68-95-99.7 rule, tells you where most of your values lie in a normal distribution: Around 68% of values are within 1 standard deviation from the mean. Around 95% of values are within 2 standard deviations from the mean.
Standard Normal Distribution Table. This is the "bell-shaped" curve of the Standard Normal Distribution. It is a Normal Distribution with mean 0 and standard deviation 1. It shows you the percent of population: It only display values to 0.01%.
A normal distribution is the bell-shaped frequency distribution curve of a continuous random variable. Visit BYJU’S to learn its formula, curve, table, standard deviation with solved examples.

Oct 3, 2018 · The empirical rule, sometimes called the 68-95-99.7 rule, says that for a random variable that is normally distributed, 68% of data falls within one standard deviation of the mean, 95% falls within two standard deviations of the mean, and 99.7% falls within three standard deviations of the mean.
