The data organized in frequency table is termed as grouped data. Strengths of Frequency Table A frequency table can split data into classes or categories. By frequency table the actual number of scores as well as the % age of scores in each interval can be displayed. A frequency table can be used to summaries categorical, nominal, and ordinal data.
