frequency
Frequency is the number of occurrences of a repeating event per unit time
histogram
A histogram is a graphical representation of the distribution of numerical data
quartile
In descriptive statistics, the quartiles of a ranked set of data values are the three points that divide the data set into four equal groups, each group comprising a quarter of the data
percentile
A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall
cumulative frequency
Cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value
data
Data is a set of values of qualitative or quantitative variables
bimodal
In statistics, a bimodal distribution is a continuous probability distribution with two different modes
