what is the relationship between mean median and mode in a symmetrical distribution 
in a symmetrical distribution all three of these descriptive statistics tend to be the same value for instance in a normal distribution bell curve this also holds in other symmetric distributions such as the uniform distribution where all values are identical depicted simply as a horizontal line or the binomial distribution which accounts for discrete data that can only take on one of two values e g zero or one yes or no true or false etc on rare occasions a symmetrical distribution may have two modes neither of which are the mean or median for instance in one that would appear like two identical hilltops equidistant from one another
