The principle of frequency distribution table.1. determine the amount of raw data, there are more or less all that?2. find the maximum or minimum value of the data that exist.3. the value of the data from the radar bills. Radar = maximum value-minimum value4. determine how many floors are divided into (5-15 top stories)5. find the width of each class from the antonphak (adjusted to 5 or top 10). The width of the layer number of layers/antonphak = radar (/= Division or section). 6. Select the minimum value, or the value of antonphak to be noticed.
