What to Focus On

  • Ungrouped data is a raw list of observations.
  • Grouped data uses class intervals and frequencies.
  • A value equal to an upper class-boundary goes to the next class.

  • Mean uses all observations.
  • Direct, assumed mean, and step-deviation methods are used for grouped data.
  • Class marks are used in grouped mean calculations.

  • Example 1 exact mean = 59.3.
  • Example 1 grouped mean = 62.
  • Assumed mean method also gives 62.

Common Mistakes to Avoid

For grouped data, the exact mean is found by using the class intervals directly instead of class marks.

The mean of grouped data and the mean of ungrouped data must always be the same for the same data.

A student scoring exactly equal to an upper class-boundary belongs to the lower class.
