What is a normal distribution?
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. The normal distribution will show as a bell curve on a graph.
The given bell curve is the curve for normal distribution which is symmetric about the mean(0). The markings on the horizontal axis for the mean, and the scores at ±1 standard deviation, ±2 standard deviations, and ±3 standard deviations will be done below as shown.
