Frequencies - Just the count or number of observations in each category. Abbreviated as 'n' or 'f' Relative Frequency - The number of times a particular observation occurs divided by the total number of observations. Frequency Distribution - A summary of the numerical counts of the values or categories of a measurement. Cumulative Frequency -The number of observations with a value less than the maximum value of the variable interval. Cumulative Relative Frequency - A number calculated...
