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

Question

State with reasons whether you agree or disagree with the following statements

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

Answer 1

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.
