The normal distribution is also known as the Gaussian distribution. The percentage of the data that will lie above the mean is 50%.
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean.
As we know that normal distribution is symmetric to the mean, therefore, If a data set is normally distributed, the percentage of the data that will lie above the mean is 50%.
