What to Focus On

  • Analysis of data extracts significant facts from numerical data.
  • Central tendency means data cluster around a central value.
  • An average is a representative value for a set of data.
  • Averages convert raw data into brief form.
  • They help in comparison between groups.
  • They provide a representative value.
  • Arithmetic mean is the mathematical average.
  • It is found by dividing the sum of items by the number of items.
  • It is a measure of central tendency.

Common Mistakes to Avoid

Arithmetic mean is the same as an actual data value and must appear in the set of observations.

Arithmetic mean can be calculated for qualitative data such as honesty, bravery, loyalty, and beauty.

In discrete series, N means the number of different x-values listed in the table.
