What to Focus On

  • Each numerical figure in a data set is called an observation.
  • Data are of two types: primary data and secondary data.
  • Raw data is original and unorganised.
  • Tabulation means arranging data in a table.
  • Frequency is the number of times an observation occurs.
  • A frequency distribution table uses tally marks.
  • Range = largest number minus smallest number.
  • Range measures spread in a data set.
  • Always identify the largest and smallest values first.

Common Mistakes to Avoid

The mean must be one of the observations in the data.

The median changes if the same data is arranged in descending order instead of ascending order.

Mode means the largest number in the data.
