The mode is the value that appears most often in a set of data

sample
In statistics, quality assurance, and survey methodology, sampling is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population

range
In arithmetic, the range of a set of data is the difference between the largest and smallest values
histogram
A histogram is a graphical representation of the distribution of numerical data
Bimodal distribution
In statistics, a bimodal distribution is a continuous probability distribution with two different modes
skewed
In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean
interquartile range
In descriptive statistics, the interquartile range , also called the midspread or middle fifty, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between the upper and lower quartiles, IQR = Q3 - Q1
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
maximum
In mathematical analysis, the maxima and minima of a function, known collectively as extrema , are the largest and smallest value of the function, either within a given range or on the entire domain of a function
