estimate of the mean from a grouped frequency table. Frequency Tables When raw data is organised it can be helpful to display it in the form of a table showing the frequency (f) with which each data item (x)occurs. Such a table is called a frequency table.However, when a larger range of data is involved it may be beneficial to first break the data down into small groups, in which case, the
