outlier
In statistics, an outlier is an observation point that is distant from other observations
bimodal
In statistics, a bimodal distribution is a continuous probability distribution with two different modes
mean
In mathematics, mean has several different definitions depending on the context
median
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half
mode
The mode is the value that appears most often in a set of data
range
In arithmetic, the range of a set of data is the difference between the largest and smallest values
standard deviation
In statistics, the standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values
variance
In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean, and it informally measures how far a set of numbers are spread out from their mean
