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.
Answer to: The normal distribution curve is sometimes symmetric to its mean True False Explain. By signing up, you'll get thousands of step-by-step...
The total area under a standard normal distribution curve is 100% (that’s “1” as a decimal). For example, the left half of the curve is 50%, or .5. So the probability of a random variable appearing in the left half of the curve is .5. Of course, not all problems are quite...

Properties of a normal distribution include: the normal curve is symmetrical about the mean; the mean is at the middle and divides the area into halves; the total area under the curve is equal to 1 for mean=0 and stdev=1; and the distribution is completely described by its mean and stdd...
Normal distribution, also known as the Gaussian distribution, is a probability distribution that appears as a "bell curve" when graphed. The normal distribution describes a symmetrical plot of data around its mean value, where the width of the curve is defined by the standard deviation. ...
those at a distance from the mean. The area under the normal distribution curve represents the probability, and the total area under the curve sums up to one. In a perfectly normal distribution, the mean, median, and mode values are the same, and they indicate the peak of the curve. ...
Bell Curve Example A good example of a bell curve or normal distribution is theroll of two dice. The distribution is centered around the number seven and the probability decreases as you move away from the center. Here is the percent chance of the various outcomes when you roll two dice. ...
