The values of Mean, Median and Mode are equal :
Answer: A
Mean, median and mode are equal in a normal distribution.
The normal curve is symmetrical and bell-shaped with a single peak, so its highest point (the mode), its middle value (the median) and its average (the mean) all fall at the same central value.
In a skewed distribution the three separate: in a positive skew the mean is pulled above the median, which is above the mode. A binomial distribution is symmetrical only when p is 0.5, and 'abnormal distribution' is not a statistical term.
