Question
There is no difference between quartiles, deciles, and percentiles.

Answer

No, I do not agree with the statement.
  • Quartiles are the values that divide the series into 4 equal parts, whereas deciles are the values that divide the series into 10 equal parts, while percentiles divide the series into 100 equal parts.
  • Quartiles consist of 3 values, while deciles are of 9 values and percentiles are of 99 values.
  • Hence, though quartiles, deciles, and percentiles are interrelated, they differ from each other.
