1. Data, Grouping, and Class Mark

  • Data may be ungrouped or grouped.
  • Ungrouped data lists individual observations directly.
  • Grouped data arranges observations into class intervals with frequencies.
2

2. Mean of Ungrouped and Grouped Data

  • Mean is the sum of observations divided by the total number of observations.
  • For data with frequencies, multiply each observation by its frequency and divide by total frequency.
  • For grouped data, class marks are used in place of observations.
3

3. Median of Grouped and Ungrouped Data

  • Median is the middle-most observation.
  • For ungrouped data, first arrange values in ascending order.
  • If n is odd, the median is the ((n+1)/2)th observation.
4

4. Mode of Grouped and Ungrouped Data

  • Mode is the value that occurs most frequently.
  • For ungrouped data, the mode is found by counting repeated values.
  • For grouped data, only the modal class can be identified directly from the highest frequency.
