The detailed shape of a normal-distribution curve is determined by its mean and standard deviation values.An experiment with a small standard deviation will produce a tall, narrow curve; whereas a large standard deviation will result in a short, wide curve.

This is true, as the standard deviation determines the spread of the data in a normal distribution curve. A small standard deviation will result in less variability and therefore a tall and narrow curve, while a large standard deviation will result in more variability and therefore a short and wide curve. The mean determines the center of the curve.
