Question

Four basketball teams took a random sample of players regarding how high each player can jump (in inches).

Team 1	Team 2	Team 3	Team 4	Team 5
36	32	48	38	41
42	35	50	44	39
51	38	39	46	40

What is the $df\left(num\right)$?

Short answer

The $df\left(num\right)$ is $4$.

Step-by-step solution

Given Information

Team 1	Team 2	Team 3	Team 4	Team 5
36	32	48	38	41
42	35	50	44	39
51	38	39	46	40

Explanation

The degree of freedom in numerator.

we calculate like:

$d{f}_{\text{num}}=k-1$, where

$k=$ the number of different groups

In our Example $k=5$, so

${\mathbf{df}}_{\text{num}}=5-1=\mathbf{4}$
