Neighborhood 1: 2 2 4 3 1 0 2 1 3 2

Neighborhood 2: 8 6 7 6 9 5 6 6 9 8

Neighborhood 3: 4 3 5 0 8 7 4 6 1 8

Answer #1

Percentile Rank is percentage of scores that equal to or less than a given value or given score.

It is calculated by formula as:

R = P / 100*(N + 1)

where R = Percentile Rank

P = Percentile and

N = Number of items

For given data values Percentile Rank can be calulated as below:

a) Percentile Rank for 4 = 4/100*(10+1) =
**0.44**

b) Percentile Rank for 7 = 7/100*(10+1) =
**0.77**

c) Percentile Rank for 2 = 2/100*(10+1) =
**0.22**
