The mean and standard deviation are the two parameters that fully describe the shape and spread of a normal distribution. The mean tells us the central tendency of the distribution, while the standard deviation tells us how much the scores deviate from the mean. Together, these two values give us a complete picture of the distribution. The other options are not sufficient to fully describe a normal distribution.
