Frequency Distributions - Cumulative Frequencies. A cumulative frequency is the number of times that a value and all values that precede it occur. That is, the frequencies accumulate over values -hence “cumulative”. The same reasoning goes for cumulative relative frequencies as shown in the figure below.

To get a 2-way frequency table (i.e. a frequency table of the counts of a data set as divided by 2 categorical variables), you can display it in a cross-tabulated format or in a list format. In R, the xtabs() function is good for cross-tabulation. Let’s use the “mtcars” data set again; recall that it is a built-in data set in Base R.

The definition of the word “frequency” is how often something occurs. So, a frequency table shows how many occurrences have taken place. You may need to count items or events to determine their frequency. The counted items are also called data. The data is placed into groups or categories. Frequency tables usually have two or more columns. ;

I recently needed to get a frequency table of a categorical variable in R, and I wanted the output as a data table that I can access and manipulate. This is a fairly simple and common task in statistics and data analysis, so I thought that there must be a function in Base R that can easily generate this. Sadly, I could not find such a function.

Summary: The CumFreq model program calculates the cumulative (no exceedance, non-exceedance) frequency and it does probability distribution fitting of data series, e.g. crop production, soil properties, salinity, depth to watertable (water-table), rainfall, river and drain discharge, groundwater (ground-water) and river level, hydraulic conductivity and soil permeability for water. The Excel FREQUENCY function returns a frequency distribution, which is a summary table that shows the frequency of each value in a range. FREQUENCY returns multiple values and must be entered as an array formula with control-shift-enter.

Draw a cumulative frequency graph and work out the L.Q, Median, U.Q and the I.Q.R. First you will need to calculate the cumulative frequencies before the curve can be drawn: 2 people scored up to 20% (2) 15 had a total score of 40% or less (2 + 13) Means, Frequency Tables, and Weighted Average. Motivation Problem. Interpret each of the numbers. How are they computed?
