Sagot :

Answer:

Quartiles: distribution is divided into quarters.

Quintiles: distribution is divided into fifths.

Deciles: distribution is divided into tenths.

Percentile: distribution is divided into hundredths.

Example:

Calculate Quartile-1, Deciles-3, Percentiles-20 from the following data

3,13,11,11,5,4,2

Solution:

Arranging Observations in the ascending order, We get : 2,3,4,5,11,11,13

Here, n=7

Q1= (n+1)th value of the observation

——

4

=(8)th value of the observation
