COMM 215 Lecture Notes - Lecture 2: Ogive, Categorical Variable, Continuous Or Discrete Variable
Document Summary
A summary of a set of data that displays the number of observations in each of the distribution"s distinct categories or classes. Contains the values of a variable (or a set of ranges within which the data falls) Also contains the corresponding frequencies with which each value occurs (or frequencies with which data fall within each range) Relative frequency the proportion of total observations that are in a given category relative frequency = frequency of the ith value of the discrete variable total numbers of observations. Discrete number data that can take on a countable number of possible values (nombre entier - e. g. : number of people) Continuous data data whose values are uncountable and that may assume any value in an interval (e. g. : time, temp, length, ) classes must be : Summarised in a grouped data frequency distribution.
