Speed Dating Some of the nonparametric methods in this chapter use ranks of data. Find the ranks corresponding to these attractiveness ratings (1 = not attractive; 10 = extremely attractive) of males by females who participated in a speed dating event (from Data Set 18 “Speed Dating”):

5, 7, 7, 8, 7.

Step by step solution

01

Given information

The provided data deals with attractiveness ratings of males by females who participated in a speed dating event.

02

Assign the ranks

Arrange the values in ascending order along with the serial number.

The rank of value 5 is equal to 1.

Here, 7 occurs thrice and occupies the positions.

The rank of value of 7 is computed as follows:

\(\begin{array}{c}Ran{k_7} = \frac{{2 + 3 + 4}}{3}\\ = 3\end{array}\)

The ranks of the three 7s areequal to 3.

The rank of value 8 becomes 5.

The following table summarizes the ranks:
