Understanding NCEA Inverse Normal Calculations Using the Graphic Calculator.

Normal distribution, also known as Gaussian distribution, is a statistical distribution that is commonly used to describe random variables that have a symmetric, bell-shaped curve.

In a normal distribution, the majority of the values in a dataset cluster around the mean, with fewer values spread out to the left and right of the mean. The distribution is characterized by two parameters: the mean (µ) and the standard deviation (σ). The mean represents the central tendency of the distribution, while the standard deviation represents the spread of the distribution.

In this video, we will learn how to use the graphic calculator to quickly calculate the inverse normal distribution problems.
