is a normal distribution symmetric or not symmetric ?

A normal distribution is symmetric. The bell curve of a normal distribution is perfectly symmetrical around its mean. This means that the left side of the distribution is a mirror image of the right side. In other words, the values on either side of the mean have equal probability, and the mean, median, and mode of a normal distribution are all equal.

**Tip:** When working with data, plotting a histogram can help you visually assess whether the distribution appears symmetric or normal.
