                                                Frequency Table

The frequency of a data value can be defined as the number of times it occurs in a given data set. A frequency table is formed when the collected data values are arranged in ascending order of magnitude along with their corresponding frequencies. We need to count the frequencies to make a frequency distribution table. The main purpose of constructing this table is to show the number of times a value occurs. This organized tabulation of the numbers in different categories on the scale of measurement. This data needs to be organized in a meaningful form so that any emerging trend can be easily seen.

Quick Facts: –

  • Relative frequency can be calculated when we arrange the values and look at the number of times an event is occurring a particular scenario.
  • A relative frequency table is form when be create a tabulation that shows the mode of a certain type of data.
  • It is important to have an idea about the range of the data set. The range is maximum and minimum values of the data set.
  • The range of the data set is divided into arbitrary intervals that are known as class intervals.
  • These class intervals need to be mutually exclusive and should not overlap each other.
  • The class width can be determined by dividing the range of observations by the number of classes.
  • While dealing with smaller data sets, equal class widths should be equal.
  • Creating a frequency distribution table allows us to have a glance at the entire data more conveniently.
