What to Focus On

  • Mean is one of the three measures of central tendency.
  • Raw data mean uses every observation directly.
  • Ungrouped frequency mean uses frequencies and values together.

  • Median depends on the middle position, not on all values.
  • Data must be arranged before finding the median.
  • For odd n, one middle observation is taken.

  • Mode shows the most common value in a dataset.
  • A dataset may have no mode.
  • A dataset may have more than one mode.

Common Mistakes to Avoid

Mean is always found by adding the observations and dividing by the number of values, even when frequency is given.

In grouped data, the class interval itself is used as the value for mean calculations.

The assumed mean must always be the exact middle value or a fixed number like 30 or 35.
