Detailed explanation-1: -The exact middle or center of a bell curve, if the data is distributed normally, is called the mean. The mean is the mathematical average. In a normal curve, the mean is also equal to the mode and the median of the data. The mode is the value which occurs the most often in the distribution.
Detailed explanation-2: -A bell curve is a graph depicting the normal distribution, which has a shape reminiscent of a bell. The top of the curve shows the mean, mode, and median of the data collected.
Detailed explanation-3: -In a bell curve, the peak represents the most probable event in the dataset while the other events are equally distributed around the peak.
Detailed explanation-4: -For a perfectly normal distribution the mean, median and mode will be the same value, visually represented by the peak of the curve. The normal distribution is often called the bell curve because the graph of its probability density looks like a bell.
